Dental Inlays Waterloo
An inlay restoration is a custom made filling made of composite material, gold, or tooth-coloured porcelain. Porcelain inlays are a popular cosmetic dentistry option because they resemble your natural tooth.
A porcelain inlay is made by a professional dental laboratory and is permanently cemented into the tooth by your Waterloo dentist.
Inlays can be utilized to conservatively repair teeth that have large defective fillings or have been damaged by decay or trauma. Inlays are an ideal alternative to conventional silver and composite fillings. Also, they are more conservative than crowns because less tooth structure is removed in the preparation of inlays.
As with most dental restorations, inlays are not always permanent and may someday require replacement. They are highly durable and will last many years, giving you a beautiful long lasting smile.
Reasons for Inlay Restorations:
- Broken or fractured teeth.
- Cosmetic enhancement.
- Decayed teeth.
- Fractured fillings.
- Large fillings.
What Does Getting an Inlay Involve?
An inlay procedure usually requires two appointments. Your first appointment will include taking several highly accurate impressions (molds) that will be used to create your custom inlay and a temporary restoration.
While the tooth is numb, the dentist will remove any decay and/or old filling materials. The space will then be thoroughly cleaned and carefully prepared, shaping the surface to properly fit an inlay restoration. A temporary filling will be applied to protect the tooth while your inlay is made by a dental laboratory.
At your second appointment your new inlay will be carefully and precisely cemented into place. A few adjustments may be necessary to ensure a proper fit and that your bite is comfortable.
You will receive care instruction at the conclusion of your treatment. Good oral hygiene practices, a proper diet, and regular dental visits will aid in the life of your new inlay.

What to Expect From an Inlay Procedure
An inlay is a custom-made restoration that fits inside the chewing surface of a back tooth, between the cusps. It is the middle option between a filling (suited to smaller damage) and a crown (suited to very large damage). Inlays are typically made of porcelain, ceramic, or gold, and they are fabricated in a dental lab rather than placed directly in the tooth like a composite filling. The standard process involves two appointments about two to three weeks apart.
At the first visit, the tooth is numbed with local anaesthetic. Your dentist removes old filling material and any decay, then shapes the area to receive the inlay. A digital scan or impression captures the prepared tooth, the bite, and the surrounding teeth. The scan is sent to the lab where the inlay is made to fit precisely. A temporary filling protects the prepared tooth while you wait.
At the second visit, the temporary is removed, the inlay is tried in to check fit and colour, and any final adjustments are made. When everything is right, the inlay is permanently bonded to the tooth with a strong dental cement that cures under a blue light. The bite is checked one more time, the surface is polished, and you are done. Most patients have full chewing function back the same day.
When an Inlay Is the Right Restoration
Inlays handle a specific range of cases where a filling would be too small and a crown would be too much. Your dentist may recommend an inlay when:
- A medium-sized cavity or fracture has damaged the chewing surface between the cusps of a back tooth
- An old filling has failed and the surrounding tooth has lost enough structure that a new direct filling would not be reliable
- The damaged area sits within the cusp boundaries — the cusps themselves are still intact and healthy
- A tooth-coloured restoration is preferred for aesthetic reasons over a metal filling
- Long-term durability matters more than the lower cost and faster placement of a composite filling
- A high-strength material like porcelain or zirconia is needed to handle heavy chewing forces in a back tooth
Where damage extends to the cusps themselves or beyond, an onlay or full crown becomes the right choice. Where damage is small and contained, a composite filling is faster and less costly. Your dentist explains which option fits your specific tooth and why.
Care and Longevity of an Inlay
A well-made and well-cared-for porcelain or gold inlay generally lasts ten to twenty years, often longer than composite fillings of similar size. Porcelain inlays resist staining and wear better than composite, while gold inlays are extremely durable and gentle on opposing teeth. The bond between the inlay and the natural tooth is the part most likely to need attention over time, particularly at the margins where the inlay meets the tooth.
Daily care is no different from caring for natural teeth: twice-daily brushing with fluoride toothpaste, daily flossing (slide rather than snap the floss between teeth), and regular cleaning visits. The hygienist checks the inlay's margins at each cleaning to catch any wear or early decay early. Patients who grind their teeth at night should wear a custom nightguard to extend inlay life and protect the surrounding teeth.
Avoid biting hard objects like ice, pen caps, or fingernails. Inlay materials are durable but not indestructible, and a fracture in the inlay or the surrounding tooth often means replacement rather than repair. Bring any new sensitivity or change in bite to your dentist's attention promptly.
Cost and Insurance Coverage
Inlay cost depends on the material chosen (porcelain, ceramic, or gold), the size of the inlay, and the lab fee for fabrication. Trillium follows the current Ontario Dental Association Suggested Fee Guide for inlay procedures, and we provide a written estimate at the planning visit so you know the cost up front. Cost is typically higher than a composite filling and lower than a full crown.
Most private dental insurance plans cover a portion of inlay cost, often at the same rate as crowns under major restorative services. Some plans cover only at the rate of a comparable composite filling, with the patient paying the difference. We submit a pre-determination to your insurer before treatment so you know your share in advance, and we can discuss payment timing options for the out-of-pocket portion.
Frequently Asked Questions
How is an inlay different from a filling?
A filling is placed directly into the cavity in liquid form, hardened with a curing light, and shaped during the same appointment. An inlay is custom-made in a dental lab to fit precisely into the prepared cavity. The fabricated approach is more durable for medium to large restorations and lasts longer, but it requires two visits rather than one.
Why not just get a crown?
A crown covers the entire tooth, which is the right choice when more than a third of the tooth has been lost. An inlay preserves the healthy cusps and only restores the damaged middle section, which keeps more of your natural tooth intact. When the cusps are intact, an inlay is the more conservative choice.
Are porcelain inlays as strong as gold?
Modern porcelain and zirconia inlays are very strong and suitable for most back-tooth applications. Gold remains the gold standard for very long-term durability and is gentler on opposing teeth, but most patients prefer the tooth-coloured appearance of porcelain. Your dentist will discuss which material fits your situation.
How long is the temporary in place?
Two to three weeks while the lab fabricates the permanent inlay. Temporary filling material is softer than permanent restorations, so avoid sticky or very hard foods on that tooth during the wait. If the temporary comes loose or out, call the office promptly so it can be replaced.
Will the inlay match my other teeth?
Porcelain and ceramic inlays are shade-matched to your surrounding teeth and look natural on a back tooth. Gold inlays are clearly visible as metal but are usually placed where they are not visible when you smile. Your dentist explains what each material looks like before you choose.
Can a tooth with an inlay still get decay?
Yes, at the margin where the inlay meets the natural tooth. This is why daily flossing around the area and regular cleaning visits matter. A small cavity caught early at the margin can be addressed; one that goes unnoticed can undermine the inlay and require replacement of both the inlay and treatment of the larger decay.
