Inlays and onlays are custom restorations that repair back teeth with moderate decay or damage. They are a more conservative option than a full crown, ideal when much of the tooth is still healthy. An inlay fits within the biting surface of the tooth, while an onlay extends to cover one or more of the cusps. Both strengthen the tooth while preserving as much natural structure as possible.

No. We numb the tooth before treatment, so the process is comfortable. Any mild sensitivity afterward typically fades within a few days.
If you have inlays or onlays that have been in place for several years, you may wonder whether replacement is necessary. A restoration that remains intact, well-bonded, and free from damage typically doesn’t need to be replaced. However, replacement is usually recommended when an inlay or onlay becomes loose, shows signs of wear or discoloration, develops decay around its edges, or if the underlying tooth structure has shifted or become compromised. You might also choose to replace an older restoration for cosmetic reasons—modern materials often provide a more natural appearance and better blend with your tooth. The team at Fullerton Smile Dentistry can evaluate your inlays and onlays and help you decide the best course of action.
Some sensitivity after inlay or onlay placement is normal and usually temporary. The tooth and underlying nerve can be slightly irritated from the preparation and fitting process, especially with deeper restorations, leading to brief sensitivity to hot, cold, or pressure. This typically settles within a few days to a couple of weeks as your mouth adjusts. If your bite feels high or uncomfortable, a quick adjustment often resolves the issue. Should sensitivity be sharp, worsen, or linger beyond a couple of weeks, reach out to Fullerton Smile Dentistry so we can examine the restoration.
Yes, although it’s uncommon, an inlay or onlay can become loose or fail over time. This may happen due to decay forming around the restoration, normal wear and tear, biting down on something hard, or the bonding material gradually weakening. If your inlay or onlay feels loose or comes out, try to save the restoration if possible, avoid chewing on that side, and keep the area clean. Contact Fullerton Smile Dentistry promptly—our team can help restore your inlays and onlays in Fullerton, CA, with re-bonding or replacement before bacteria reach the tooth and cause decay or sensitivity.
