What kind of doctor provides Inlays Onlays?
A dentist usually places inlays and onlays. Some dentists have extra training in restoring damaged teeth and are called prosthodontists, specialists in replacing or repairing teeth. Your regular dentist can tell you whether they can do the work or whether you should see a specialist.
What it is
An inlay or onlay is a solid piece of material that a dentist bonds into or onto a damaged tooth. An inlay fits inside the cusps, the raised bumps on top of the tooth; an onlay covers one or more cusps. Both are usually made from porcelain, a hard ceramic material, or a gold alloy.
Why a doctor might recommend it
Dentists suggest inlays and onlays when a tooth has decay or an old filling is worn out, and the tooth is still strong enough that a full crown is not needed. Because they are made outside the mouth, they fit tightly and hold up well over time.
How to prepare
- Tell your dentist about all medicines you take and any health conditions you have.
- Ask whether you will need someone to drive you home if you receive medicine to help you relax.
- Eat normally before your visit unless your dentist tells you otherwise.
- Plan for about one to two hours at the office for the first visit.
What happens during it
The dentist numbs the area around the tooth and removes the decay or old filling, then takes a mold or digital scan and places a temporary filling while a lab makes the inlay or onlay. At a second visit, the dentist bonds the finished piece in place and polishes it to match your bite.
Recovery
Most people can go back to school or work the same day. Mild soreness usually fades in a day or two, and your dentist may suggest avoiding very hard or sticky foods while the bonding fully sets.
Risks and side effects
Serious problems are rare. Some people have temporary sensitivity to hot or cold, or soreness in the gum near the treated tooth. In a few cases the tooth can crack later or the piece can loosen, which means the dentist needs to check it.
Who performs it
General dentists perform most inlay and onlay procedures. If your case is complex, your dentist may send you to a prosthodontist.
How a direct primary care or concierge doctor fits in
They do not place inlays or onlays, but a direct primary care or concierge doctor can help with the health side of dental care by treating infections around the mouth, reviewing medicines that affect dental work, and managing conditions like diabetes that affect healing. If you have mouth pain, a primary care doctor can be a good first stop to rule out other causes and point you to the right specialist.
Common questions
How long does an inlay or onlay last?
Many last ten years or more with good brushing and regular dental checkups, but this varies from person to person. Is the procedure painful? The area is numbed first, so most people feel little more than pressure during the visit. Does insurance cover it? Many dental insurance plans cover part of the cost, but coverage varies, so check with your plan. Can I eat right after? It is usually best to wait until the numbness wears off so you do not bite your cheek or tongue.
