Amalgam Separator Installation & Service in Los Angeles County · page →
If you place or remove dental amalgam, the EPA Dental Rule requires a compliant separator. We can help.
Most manufacturers recommend service when the container is full or on a set schedule. We keep you on track.
We coordinate with certified recyclers for proper handling and documentation.
Yes. We install all major brands and integrate with your existing systems.
Yes — a trip charge based on distance from our City of Industry shop. Your office is inside our 30-mile service area if it is on our service-area list, and we quote the trip charge before we schedule the visit. Labor is billed by time on site and parts are quoted before they are installed.
One that is sized for the chairs that run at once and fits your vacuum line. We install the common makes and quote the unit, installation and canister service in writing; tell us your operatory count.
We coordinate the spent canister with a certified recycler and give you the service and recycling records for your compliance file; the practice keeps and files the program.
Yes, when it is full or the solids collector is blocked. It is one of the first things checked on a vacuum pump call.

Dental Chair Repair in Los Angeles County & San Gabriel Valley · page →
For emergencies, we dispatch same-day. Most chair repairs are completed in a single on-site visit. If parts are needed, we prioritize scheduling.
Yes. We service A-dec, Pelton & Crane, Midmark, Belmont, DentalEZ, and every other major brand with access to OEM and aftermarket parts.
Costs depend on the specific issue. We provide an estimate in advance, and we quote the trip charge — based on distance from our City of Industry shop — before we schedule.
Yes. We offer full reupholstery with a selection of medical-grade materials and colors.
Yes. A-dec, Midmark, Pelton & Crane, Belmont, DentalEZ, Marus, DCI, Royal and Engle chairs and delivery units are the ones we service every week across LA County.
Yes. We disconnect, move and reinstall chairs, delivery units and lights, in the same office or to a new address; see equipment relocation.
Get the diagnosis first: a drifting chair is often a seal, not a chair. When the core is worn out, we can quote a refurbished chair and delivery unit rebuilt in our shop, installed by the same technicians.
Repair services
Dental Air Compressor Repair in Los Angeles County & San Gabriel Valley · page →
In most cases, yes. Pressure issues are our most common compressor call. We dispatch same-day and carry frequently needed parts.
Yes. If your compressor needs off-site repair, we provide a loaner unit to keep your practice running.
We recommend professional maintenance every 6 to 12 months. Regular servicing prevents sudden failures.
Yes. Our technicians handle both system types from every major manufacturer.
Yes. We install compressors regardless of where they were purchased, with the power, ventilation and piping checked first; see installation.
By what is worn. Heads, valves, dryers and switches are repairable; a unit that is undersized for your operatories or has a failed core is a replacement. We quote a repair in writing first and, if it is time, a refurbished compressor or a new Tech West unit.
Yes. Filters, dryer and desiccant, tank drain and a pressure and leak check on a scheduled preventive-maintenance visit, usually every six months for a busy office.
Repair services
Dental Curing Light Repair in Los Angeles County · page →
Usually output loss: a contaminated or chipped light guide, a tired battery that cannot hold voltage through a cycle, or an LED module or bulb past its life. We measure the output first; a cleaning or a light-guide replacement is sometimes all it takes.
Yes. We measure irradiance before and after any repair and tell you the number, so you know whether the light is curing to your material's requirements.
Yes. Battery packs and charging bases are the most common curing light repair. If the model's battery is no longer available, we tell you plainly and help you decide whether to retire the light.
A curing light is small enough to bring to our City of Industry shop or to add to a scheduled service call. For a dedicated visit, there is a trip charge based on distance from our shop, quoted before we schedule.
When the output cannot be restored to what your materials require, when parts for the model are no longer available, or when the repair cost approaches a new light. We tell you which case you are in before you spend anything.
Repair services
Dental Equipment Relocation & Moving in Los Angeles County · page →
Yes. Single-operatory moves within an office are common when a room is repurposed. We disconnect, move and reconnect the chair, delivery unit and light and test them in the new room.
Yes. Equipment-room units are disconnected, transported and reinstalled, with the new room's power, ventilation, drain and piping checked before the move so the units run on day one.
By distance and scope: the number of units, the two addresses and what the new site needs. The quote is written and includes disconnection, transport, reinstallation and testing.
Yes. We relocate and reinstall the brands we service regardless of where the equipment was bought.
Ask. Equipment delivery and installation cover all of California; relocation jobs beyond our 30-mile repair area are quoted case by case.
Repair services
Dental Handpiece Repair in Los Angeles County & San Gabriel Valley · page →
Most high-speed repairs are completed within a few business days.
Repair is usually far more cost-effective. A turbine replacement restores near-new performance at a fraction of the cost.
Yes — KaVo, NSK, Bien-Air, W&H, and others.
Yes. We offer pickup and delivery throughout our service area.
Yes. KaVo, NSK and Midwest high-speed, low-speed and electric handpieces are the ones we repair most. Other makes: tell us the model and we will confirm.
A pickup is a service visit, so the trip charge applies, quoted by distance from our City of Industry shop before we schedule. Adding handpieces to a service call that is already booked avoids a separate trip, and you can drop them at the shop.
Lubrication and sterilization routine, mostly; see high-speed handpiece maintenance. Wet air from a tired compressor dryer is the other big cause.
Repair services
Dental Operatory Light Repair in Los Angeles County & San Gabriel Valley · page →
Yes. Loose arms are one of our most common light repair calls. We adjust or replace the spring mechanism.
Yes — LED and halogen, including module replacement and driver board repair.
Yes. All mounting configurations from all manufacturers.
Cost depends on the issue. We provide upfront estimates, and we quote the trip charge — based on distance from our City of Industry shop — before we schedule.
Often, yes, with a retrofit module or an LED head for the mount you have. We check the arm, wiring and transformer first so the retrofit holds up.
Yes. Output testing, batteries, light guides and switches; see curing light repair.
Usually. Arm tension springs, friction joints and mounts can be adjusted or replaced; a drifting arm is one of the most common light repairs.
Repair services
Dental Autoclave & Sterilizer Repair in Los Angeles County & San Gabriel Valley · page →
Yes. We diagnose the root cause — gasket, element, sensor, or board — and repair it so your unit passes consistently.
Yes. We maintain loaner autoclaves so your practice continues operating during repair.
Many issues are resolved on-site. Complex repairs typically take 48-72 hours at our facility.
Yes, along with traditional chamber-style autoclaves from all manufacturers.
Many Midmark, Statim and Tuttnauer codes point to a specific part; our free online troubleshooter reads the code and tells you the safe user-level checks. If it is a technician job, we tell you that too.
Gaskets, valves, elements and sensors are repairable; a chamber or a board on a discontinued model may not be worth it. We quote the repair first and can quote a refurbished, spore-tested sterilizer if it is time.
On installation and on preventive-maintenance visits we walk your team through the loading, water and logging routine. California requires weekly biological monitoring; the program itself stays with your infection-control lead.
Repair services
Dental Vacuum Pump Repair in Los Angeles County & San Gabriel Valley · page →
Most likely. Weak suction across all chairs typically points to the central vacuum pump. We diagnose and repair on-site.
Yes. We maintain loaner units so your practice never shuts down during a vacuum pump repair.
We dispatch same-day from City of Industry. Our 30-mile radius covers most of LA County.
Yes. All types and brands.
Yes. A full separator or a blocked solids collector drops suction at the chairs, so it is checked on every vacuum call; we service and replace separators too.
Vanes, seals, bearings and motors are repairable; a pump that is undersized for the chairs that run together is a replacement. We quote the repair first and can quote a refurbished pump or a new Tech West system if it is time.
Yes. We install vacuum pumps regardless of where they were bought, with drain, water, exhaust and power checked first.
Repair services
Dental Unit Waterline Shock Treatment & Testing in LA County · page →
Follow your infection-control program and the current CDC guidance for the frequency; many practices test quarterly and after any shock treatment or failed result. We can set the schedule up with you and perform the testing.
The CDC's standard for non-surgical dental treatment water is the EPA drinking-water limit of 500 CFU/mL of heterotrophic bacteria or lower. We give you the number for every line we test.
We shock and flush in one visit and sample for testing; results come back from the testing process, not instantly. If a line fails we return to re-treat and retest.
Yes — a trip charge based on distance from our City of Industry shop, quoted before we schedule. Combining waterline service with a preventive-maintenance visit shares one trip.
We set up the routine with the product you choose and can supply it as part of the visit; tell us what the practice has used so far and we will advise.
Repair services
Dental X-Ray Repair in Los Angeles County & San Gabriel Valley · page →
Many sensor failures are cable or connection issues, which are repairable. We diagnose first and recommend repair when viable.
Yes — Dentsply Sirona, Carestream, Planmeca, Vatech, and others.
We prioritize X-ray failures and dispatch same-day for urgent calls.
We support compliance with California radiation safety requirements.
Yes. Gendex and Belmont intraoral and panoramic systems are the ones we service. For other brands, send the make and model first.
Yes. Arms and wall mounts are removed, moved and reinstalled as part of equipment relocation; registration of x-ray equipment with the state stays the practice's responsibility and we point you to it.
Arms, timers, switches and many tubehead faults are repairable. We take a repair-first approach and tell you in writing when replacement is the better call.
Repair services
Dental Equipment Preventive Maintenance Visits in LA County · page →
No. We do not sell maintenance contracts or plans; preventive-maintenance visits are scheduled and quoted like any service call. If a plan becomes available we will publish its terms here.
Every six months is a common interval for compressors, vacuum pumps and sterilizers in a busy office; some practices choose annual visits for lightly used equipment. We suggest an interval after seeing your equipment.
The trip charge is quoted by distance before we schedule, the visit is billed by time on site, and parts are quoted before they are installed. We do not publish amounts because offices differ; ask when you call.
No. It catches the wear items that cause most failures and tells you what to budget for; it cannot prevent every fault. It does make the emergency call less likely and the repair cheaper when one happens.
Yes. Waterline shock and testing and separator checks can be added to the same visit, sharing the one trip.
Repair services
Ultrasonic Scaler & Cavitron Repair in Los Angeles County · page →
Yes. Dentsply Cavitron countertop units and built-in scalers are the ones we see most. Tell us the model and the symptom; cable, water-flow and power faults are the usual repairs.
Usually, yes. Water-flow problems are typically a clogged filter, a stuck solenoid or a blocked handpiece line. We check the water path end to end before replacing parts.
Yes. Built-in scalers share power and water with the delivery unit, so the diagnosis covers both. We service the delivery units of all the chair brands we work on.
Yes — a trip charge based on distance from our City of Industry shop, quoted before we schedule. A countertop unit can also be brought to the shop.
If the unit needs a main board and parts are scarce, replacement can be the better call. We tell you the repair cost in writing before you decide, and we can quote a new unit if you want to compare.
Emergencies
Autoclave Failing Spore Test? Emergency Sterilizer Repair · page →
Stop using it immediately. Call us — we deliver a loaner sterilizer and diagnose your unit.
Usually same business day from our City of Industry facility.
Worn door gasket, failing heating element, or faulty temperature sensor — all repairable.
CDC guidelines recommend reprocessing instruments since the last successful test. We get your sterilizer fixed ASAP.
Many causes can be fixed on-site or within 48-72 hours. The loaner keeps you running.
Emergencies
Dental Compressor Not Building Pressure? Same-Day Fix · page →
Usually worn head valves, clogged intake filter, or leaking check valve. We carry all these parts.
Likely a capacitor, pressure switch, or thermal overload. We carry these on-truck.
Should be addressed promptly — continuous running can overheat the motor. Call for same-day service.
Yes. Available for off-site rebuild situations.
Common repairs are very affordable. We quote the trip charge before we dispatch and estimate the repair before starting.
Emergencies

Emergencies
Weekend Dental Equipment Emergency Repair in Los Angeles · page →

Depends on availability and location. Call for a current estimate.

Emergencies
Dental X-Ray Sensor Repair Near City of Industry · page →
Yes, in many cases. Most failures we see are cable, connector, or software issues — all repairable.
Depending on the brand and issue, repairs can save $3,000 to $10,000 vs. replacement.
Gendex and Belmont systems, and we will tell you plainly whether another make is one we can take on; send the make and model.
That is what our diagnostic visit determines. We test every component in the chain.
Intermittent problems are almost always cable or connection issues — one of the most repairable problems.
Used & refurbished equipment
Used & Refurbished Dental Equipment · page →
Possibly. Inventory changes week to week, so the honest answer is to call 626-422-2315 or send the form with what you need. We will tell you what is in the shop today, what is mid-refurbishment, and what we can source.
It depends on the unit, its age and what it includes, so we quote each unit individually and in writing, with delivery and installation listed separately. For a sense of the market, read our guide on what a used dental chair costs.
Yes. Ask for current photos and the unit's history, and a visit to our City of Industry shop can be arranged by appointment.
Our own technicians. Delivery, connection to air, water, vacuum and power, testing and a handover are part of the installation quote. If your office needs electrical or plumbing work first, we tell you before the unit ships.
Yes. Equipment sales, delivery and installation cover all of California. Most of our deliveries are across Southern California, from Santa Barbara and Ventura counties down to San Diego and out to the Inland Empire. Delivery and installation are quoted by distance from our City of Industry shop, and the quote is in writing before anything is scheduled.
Yes. Every refurbished unit we sell comes with a warranty. The period depends on the equipment type and its condition, and the exact terms are written into your quote so there is nothing to interpret later.
No. We do not buy doctors' equipment and we do not take trade-ins. The units we refurbish come through our own channels, and we only list a unit once it is in our shop.
Pricing
How Our Pricing Works · page →
Because every visit is different: distance, the equipment, the parts and how long the repair takes. Publishing one number would be wrong for most offices. What we do publish is how the invoice is built, and we quote the trip charge before we schedule.
Trip charge based on distance from our City of Industry shop — we quote it before we schedule. The 30-mile service area is where we go on site; the trip charge still applies inside it.
By time on site. The technician diagnoses first; if the repair is more than a wear part, you hear the scope before the work continues.
Parts are quoted before they are installed and listed on the invoice. We use OEM parts where they exist and tell you when an aftermarket part is the sensible choice.
Emergency calls are answered 7 days a week and the trip charge is quoted before we dispatch, the same way as any visit. Ask when you call.
A pickup is a visit, so the trip charge applies. Adding handpieces to a service call that is already booked avoids a separate trip, and you can drop them at the shop.
Loaner compressors, vacuum pumps and sterilizers are arranged case by case when a repair cannot be finished on the spot. Ask whether one applies to your call.
Each unit is quoted individually and in writing: the unit, its warranty, delivery and installation. Delivery and installation are quoted by distance. New Tech West equipment and refurbished units follow the same rule.
About us
About MS Dental Works · page →
Our own technicians, dispatched from the City of Industry shop. We do not subcontract service calls, and the people who install a unit are the people who service it afterwards.
Both, in that order. Repair and maintenance are the core of the business; we are also a Tech West dealer for new compressors and vacuum systems, and we sell refurbished equipment rebuilt in our shop.
Yes. Service is available in English and Spanish, on the phone and in the office.
On-site repair within about 30 miles of City of Industry across Los Angeles County, the San Gabriel Valley and north Orange County, with the trip charge quoted by distance. Equipment sales, delivery and installation cover all of California.
Loaner compressors, vacuum pumps and sterilizers are arranged case by case when a repair cannot be finished on the spot, so the practice keeps producing.
Equipment down, or planning ahead?
Call 626-422-2315, or send the service request.
Emergency calls are answered 7 days a week. For anything else, the online request reaches a technician, not a call center.
