When Should You Choose an Inlay or Onlay for a Damaged Tooth?
January 1, 2026You bite into something firm and feel a sharp twinge in a tooth. Damage like this can raise a real question. Does the tooth need a small filling, a full crown, or something in between? That “in between” option is often an inlay or an onlay.
Both are custom-made restorations that help repair moderate damage without removing more healthy tooth than needed. If you are searching for inlays & onlays in Jacksonville, FL, you may already suspect that a simple filling is not enough, yet a crown might feel like too big a step. Knowing when these restorations are used can make your next visit feel less uncertain.
What Are Inlays and Onlays?
Inlays and onlays are lab-made pieces that bond to a tooth to restore its shape and strength.
- An inlay fits inside the grooves on the chewing surface of a tooth. It does not cover the cusps, or pointed parts, of the tooth.
- An onlay covers one or more cusps and can extend over the biting surface. Some people call it a “partial crown.”
Dentists may use porcelain, zirconia, or composite resin so the restoration can closely match your natural tooth color. Because inlays and onlays are created outside the mouth, they are precise and can be shaped for a snug fit.
These restorations are often an alternative to large fillings. When a cavity or fracture is too big for a standard filling, but the tooth structure is still strong, an inlay or onlay can be a conservative choice.
Signs You May Need an Inlay or Onlay
Only a dentist can tell you for sure which treatment is best. Still, there are common signs that an inlay or onlay may be recommended:
- You have a cavity that is too large for a simple filling.
- An old filling has cracked, leaked, or fallen out.
- Part of a tooth has broken off, but most of the structure remains sound.
- You feel pain when chewing on one side, but a full crown might not be needed.
- A tooth has hairline cracks that need extra support.
These issues often show up during a routine exam and X-rays with a dentist in Jacksonville, FL. If you have noticed a chip, sensitivity to cold, or food getting trapped in a certain area, mention it during your visit. Early treatment gives you more options and helps preserve more natural teeth.
Benefits of Inlays and Onlays
Inlays and onlays can offer several advantages:
- Conserve healthy tooth structure. Less drilling is needed than with a full crown in many cases.
- Strengthen the tooth. The bonded restoration can help support weakened areas and spread chewing forces.
- Natural appearance. Tooth-colored materials blend in, which matters for teeth that show when you smile.
- Durability. With good care, these restorations can last for many years.
- Better fit than very large fillings. Because they are made in a lab, inlays and onlays are shaped to fit your tooth’s unique contours.
They can also be part of a broader treatment plan. For example, if you have worn or cracked teeth from grinding, your dentist might combine inlays, onlays, and dental crowns in Jacksonville, FL, to rebuild your bite.
When to See a Dentist
Any time you notice a change in a tooth, it is wise to schedule an exam. Call a dentist if you:
- Feel sudden pain when you bite or chew
- Notice a chip, crack, or lost filling
- See a dark spot that does not brush off
- Have sensitivity to hot, cold, or sweets that does not fade
Even if you are not sure something is wrong, a preventive visit helps catch small problems before they grow. Regular checkups also give you time to ask about options like onlays, crowns, or other services, such as cosmetic dentistry in Jacksonville, FL, or emergency dental care in Jacksonville, FL, when you need urgent help.
During your visit, your dentist will:
- Ask about your symptoms and health history.
- Examine your teeth and gums.
- Take X-rays if needed to see decay or cracks between teeth.
- Explain whether an inlay, onlay, filling, or crown is the best way to repair the tooth.
Final Thoughts
Choosing between a filling, inlay, onlay, or crown can feel like a big decision when you want to protect a tooth for the long term. Inlays and onlays fill an important role. They help repair teeth that are too damaged for a simple filling, yet do not need the full coverage of a crown.
