Dental Inlays & Onlays
in Fitchburg, MA
A conservative, durable solution for restoring damaged teeth, preserving more of your natural tooth structure than a traditional crown.
A Conservative Alternative to a Full Crown
When a tooth has more damage than a standard filling can address, but not enough to require a full crown, an inlay or onlay offers a precise, conservative middle-ground solution. These custom-made restorations fit directly into or onto the damaged area of the tooth, preserving significantly more of your natural, healthy tooth structure than a crown would require while still providing the strength and durability needed to restore full function.
At Rollstone Family Dental, we provide inlays and onlays for patients across Fitchburg, Leominster, Lunenburg, Townsend, Ashburnham, and Ayer dealing with moderate tooth decay, fractured fillings, or teeth that have more damage than a filling alone can repair. Our team will evaluate your specific situation and recommend the most conservative, effective option to restore your tooth.
Inlay vs. Onlay: What's the Difference?
Both inlays and onlays are custom-made restorations used to repair a tooth with more damage than a filling can address, but they differ in how much of the tooth they cover.
- An inlay fits within the grooves of the tooth's chewing surface, between the cusps (the raised points of the tooth).
- An onlay, sometimes called a partial crown, covers one or more of those cusps as well, providing additional coverage and support for a tooth with more extensive damage.
The right choice depends entirely on the extent and location of the damage to your tooth. During your exam, we'll determine which option provides the right balance of conservative tooth preservation and structural support for your specific situation.

Why Patients Choose Inlays & Onlays
- Preserves More Natural Tooth Structure - Unlike a crown, which requires reshaping the entire visible portion of the tooth, an inlay or onlay only addresses the specific damaged area, preserving significantly more healthy tooth structure.
- Highly Durable - Made from strong materials like porcelain or gold, inlays and onlays are built to withstand the same chewing forces as natural teeth and resist wear well over time.
- Natural Appearance - Porcelain and composite inlays and onlays can be shade-matched to your surrounding teeth, blending in seamlessly with the rest of your smile.
- A Precise Fit - Because inlays and onlays are custom-fabricated outside the mouth before being bonded into place, they offer an exceptionally precise, well-sealed fit compared to a direct filling.
Have a Damaged Tooth That Needs More Than a Filling?
If a cavity or fracture is too extensive for a standard filling but doesn't require a full crown, an inlay or onlay may be the right solution. Schedule a consultation today and our team will evaluate your tooth and recommend the most conservative, effective option.
Frequently Asked Questions About Dental Inlays & Onlays
An inlay fits within the grooves of a tooth's chewing surface, between the cusps. An onlay covers one or more cusps as well, offering more coverage. A crown covers the entire visible portion of the tooth. The right choice depends on how much of the tooth structure has been damaged — inlays and onlays are more conservative options reserved for moderate damage, while crowns are used for more extensive damage.
We use local anesthesia to fully numb the area before preparing your tooth, so you shouldn't feel pain during the procedure — only pressure. Mild sensitivity is normal for a day or two afterward, particularly to temperature, but this typically resolves quickly.
The process typically requires two visits spaced about one to two weeks apart — one for preparation and impressions, and one for placing your permanent restoration once it's been fabricated. A temporary restoration protects your tooth in between visits.
With proper care, inlays and onlays — particularly those made from porcelain or gold — can last 10 to 20 years or longer. Longevity depends on the material chosen, your oral hygiene habits, and how the restored tooth holds up to daily wear.
Porcelain and composite resin inlays and onlays can be shade-matched closely to your surrounding teeth for a natural, seamless appearance. Gold restorations, while not tooth-colored, are sometimes chosen specifically for their strength in back teeth where aesthetics are less of a priority.
For minor decay, a standard filling is often sufficient and more conservative. Inlays and onlays are recommended specifically when the damage is too extensive for a filling to provide adequate strength and support, but not extensive enough to require a full crown. Your dentist will recommend the most appropriate, conservative option based on the extent of your tooth's damage.
You'll care for the tooth just as you would any other — regular brushing, flossing, and routine checkups. There's no special maintenance required, though it's wise to avoid biting down on extremely hard foods that could damage the restoration over time.
Most dental insurance plans provide at least partial coverage for medically necessary inlays and onlays, though coverage amounts vary by plan and material chosen. We verify your insurance before your appointment and give you a clear cost estimate in advance. We do not currently accept MassHealth.
