What Are Inlays and Onlays?
Our goal is always to preserve as much of your natural tooth as possible. An inlay or onlay is a custom-made restoration that repairs a tooth that is too damaged for a filling but does not need a full dental crown. An inlay fits inside the chewing surface of the tooth, while an onlay covers one or more of the chewing cusps. Both are designed to restore the strength and function of your tooth while preserving as much healthy tooth structure as possible.
When Are Inlays and Onlays Recommended?
An inlay or onlay may be recommended when a cavity or fracture is too large for a filling but not severe enough to require a crown. They are also used to replace large, worn fillings that no longer provide enough support for the tooth. During your visit at Gleam Dentistry on Coffee Road in Modesto, we will carefully examine your tooth and take digital X-rays when needed to determine whether a filling, an inlay or onlay, or a crown is the best treatment for your situation.
Why Not Just Get a Filling or a Crown?
Many patients ask why they need an inlay or onlay instead of a filling or a crown. The answer depends on how much healthy tooth structure remains. A filling works well for small areas of damage, while a crown is recommended when the tooth has lost a large amount of its strength. An inlay or onlay is the middle option. It provides more support than a filling while preserving more of your natural tooth than a crown. When possible, our goal is always to choose the most conservative treatment for your smile.
What to Expect During the Procedure
Getting an inlay or onlay usually takes two visits. During the first appointment, any decay or damaged tooth structure is removed, and the tooth is prepared. Digital scans or impressions are then taken so your custom restoration can be made. A temporary restoration may be placed to protect your tooth while your final inlay or onlay is being created. During your second visit, the restoration is bonded to your tooth, your bite is checked, and any final adjustments are made to ensure a comfortable fit.
Long-Term Care, Cost, and Insurance
With good oral hygiene and regular dental checkups, an inlay or onlay can last for many years. Brushing, flossing, and avoiding habits such as chewing on ice or hard objects can help protect your restoration. The cost depends on the size of the restoration and the material used. Because inlays and onlays are considered restorative treatments, many dental insurance plans cover a portion of the cost. Our team will review your insurance benefits, explain your treatment options, and answer any questions before treatment begins so you can make an informed decision about your care.
Frequently Asked Questions
- Will getting an inlay or onlay hurt?
Getting an inlay or onlay should not hurt because the tooth is numbed with local anesthesia before the procedure begins, so you should not feel pain during treatment. Mild sensitivity afterward is normal and usually improves within a few days. You may experience some gum tenderness around the treatment area. - How long does an inlay or onlay appointment take?
An inlay or onlay appointment usually takes about one to two hours, depending on the size and location of the tooth being treated. - Can I eat with my temporary restoration?
You can eat with your temporary restoration, but it is best to avoid very hard, sticky, or chewy foods until your permanent inlay or onlay has been placed. - What materials are inlays and onlays made from?
Inlays and onlays are commonly made from porcelain, ceramic, or composite materials. Your dentist will recommend the material that is best for your specific situation. - Will my inlay or onlay match my natural teeth?
Your inlay or onlay will be custom-made to match the color and shape of your surrounding teeth, creating a natural-looking result. - Can an inlay or onlay come loose?
An inlay or onlay can become loose or damaged over time, although it is designed to last for many years. If you notice any movement or discomfort, contact our office so we can evaluate it. - Can I brush and floss normally after getting an inlay or onlay?
You can brush and floss your restored tooth just as you would your natural teeth. Good oral hygiene helps protect both the restoration and the tooth underneath. - Can I grind my teeth if I have an inlay or onlay?
Grinding your teeth can place extra pressure on your restoration. If you grind your teeth while sleeping, your dentist may recommend wearing a night guard to help protect your teeth. - What happens if I do not restore a damaged tooth?
A damaged tooth can become weaker over time and may continue to crack or decay. Treating the problem early with an inlay or onlay may help prevent the need for a crown, root canal, or extraction later. - Can an old inlay or onlay be replaced?
An old inlay or onlay can be replaced. Like other dental restorations, inlays and onlays may eventually need to be replaced because of normal wear, damage, or new decay around the tooth. If replacement is needed because of new dental decay, you may need a dental crown. - Are inlays and onlays stronger than fillings?
In many cases, inlays and onlays are stronger than fillings. Because they are custom-made outside the mouth and bonded to the tooth, they often provide more strength than a large filling while preserving more natural tooth structure than a crown. - How do I know if I need an inlay, an onlay, or a crown?
Whether you need an inlay, an onlay, or a crown depends on how much healthy tooth structure remains. During your examination, your dentist will evaluate the tooth and recommend the treatment that provides the best long-term result while preserving as much of your natural tooth as possible.
