Onlays in Westlake Village
When a filling has cracked, or a cavity has worn away one of the raised points on a back tooth, a standard filling often can't hold up and a full crown may remove more healthy tooth than you need to lose. That middle ground is where an onlay fits. At 805 Dentistry, our Thousand Oaks office welcomes Westlake Village patients who want to repair a damaged molar or premolar while keeping as much of their natural tooth as possible.
An onlay is a custom-made restoration that covers the chewing surface of a back tooth and extends over one or more of its cusps, the raised points that do much of the work when you bite and grind food. It is sometimes described as a "partial crown" because it restores the damaged portion of the tooth instead of capping the entire thing. We also offer inlays, which sit within the grooves between the cusps. When the damage reaches a cusp, an onlay is usually the better fit.
Because an onlay is shaped to match your tooth outside the mouth and then bonded in place, it can reinforce a weakened tooth in a way a filling packed directly into a large cavity sometimes can't. Our practice has an on-site dental lab, which helps our team coordinate closely on the shape and fit of restorations like onlays.
Onlays are a good match for many Westlake Village adults with moderate damage to a back tooth: too much for a filling, not enough to justify a full crown. Common examples include an older filling that has started to fracture, decay that has reached a cusp, or a tooth with a chipped corner from biting something hard. Our team also treats cracked teeth, so if a crack is part of the picture, we can evaluate it as part of the same visit.
Not every tooth is a candidate. If decay or a fracture has spread across most of the tooth, a crown may offer better protection. If the nerve is involved, root canal therapy may need to come first. If the gums or supporting bone need attention, our periodontal care can address that. We start with a dental exam and the imaging your situation calls for, then explain which option makes sense and why.
What happens during onlay treatment?
Onlay treatment usually takes two visits: one to prepare the tooth and one to place the finished restoration. At the first appointment, we numb the area, remove the decay or failing filling material, and shape the tooth so the onlay will fit securely. We then record the shape of the prepared tooth so the restoration can be made to match it, and we protect the tooth until your next visit.
At the second appointment, we check the onlay's fit and your bite, make any needed refinements, and bond it permanently to the tooth. For patients who feel nervous about dental work, we offer sedation options including nitrous oxide, oral sedation, and IV sedation, and a board-certified dental anesthesiologist is on our team. Here's what to expect along the way:
- A thorough exam to confirm an onlay is the right choice
- Local anesthetic so the tooth is numb during preparation
- Removal of decay or old filling material while preserving healthy structure
- A protective step between visits while your onlay is made
- A careful bite check before final bonding
How do I care for an onlay afterward?
You care for an onlay much like a natural tooth: brush twice a day, floss daily, and keep up with regular checkups. Mild sensitivity in the treated tooth for a short time after placement is common. If your bite feels uneven or discomfort lingers, call us so we can check the fit.
Routine dental cleanings and exams let us monitor the edges of the onlay, where it meets your natural tooth, and catch any new decay early. If you clench or grind your teeth, ask us about a night guard. Our practice also has a strong focus on TMJ treatment, so if jaw tension is putting stress on your teeth, we can look at that too. And if something feels wrong between visits, we offer emergency dental appointments.
How can I pay for an onlay?
We accept all major PPO insurance plans and are happy to work with self-pay patients. Coverage for onlays varies from plan to plan, so our team can help you understand what your policy may contribute before treatment begins.
We also offer financing for patients who would like to spread out the cost. When you call or visit, just ask and we'll walk you through the options. Families from Westlake Village often appreciate that our office serves children and adults alike, so one practice can handle onlays, cleanings, orthodontics, and more. Contact 805 Dentistry to schedule an exam and find out whether an onlay is the right way to restore your tooth.
