Dental Inlays and Onlays in Kanata
Conservative Restorations for Damaged Teeth
Dental inlays and onlays are restorative treatments used to repair teeth that are too damaged for a simple filling but may not need a full dental crown. At March Dental in Kanata, inlays and onlays can help restore strength, function, and appearance while preserving as much natural tooth structure as possible. They are often recommended for back teeth affected by larger cavities, cracks, worn fillings, or moderate damage.
An inlay fits within the grooves of the tooth, while an onlay covers one or more of the tooth’s cusps. Both are custom-made to fit the tooth precisely and are designed to support comfortable chewing. Because they are stronger and more durable than many standard fillings, inlays and onlays can be a good option when a tooth needs added protection without covering the entire tooth.
March Dental provides dental inlays and onlays for patients in Kanata, Stittsville, Carp, Constance Bay, Arnprior, Smiths Falls, Ottawa, and surrounding communities.
When Are Inlays or Onlays Recommended?
Your dentist may recommend an inlay or onlay when a tooth has moderate decay or damage that cannot be repaired predictably with a regular filling. This may happen when an old filling is large, cracked, leaking, or failing, or when a cavity affects a larger portion of the tooth. In these cases, placing another filling may not provide enough strength for long-term function.
Inlays and onlays may also be recommended for teeth with cracks, fractured cusps, or damage caused by grinding and chewing pressure. They can help reinforce the tooth while maintaining more natural structure than a full crown.
During your appointment, your Kanata dentist will examine the tooth, review any necessary X-rays, and discuss whether a filling, inlay, onlay, or crown is the best option. The goal is to choose the most conservative treatment that still gives the tooth the support it needs.
Benefits of Dental Inlays and Onlays
One of the main benefits of inlays and onlays is that they preserve natural tooth structure. Since they only cover the damaged or weakened portion of the tooth, they can be less invasive than a crown in suitable cases. This makes them a valuable option for patients who want strong, long-lasting restoration while keeping as much of their own tooth as possible.
Inlays and onlays are also custom-made for a precise fit. This can help create a tight seal, restore chewing surfaces, and reduce the risk of food trapping around the restoration. When made from tooth-coloured materials, they can also blend naturally with the surrounding teeth.
These restorations are designed to handle chewing pressure, making them especially useful for molars and premolars. With good home care and regular dental visits, they can provide durable support for many years.
What to Expect During Treatment
The process begins with a careful assessment of the affected tooth. Your dentist will remove decay or damaged filling material, clean the tooth, and shape it for the restoration. In many cases, a scan or impression is taken so the inlay or onlay can be custom-made to fit your tooth and bite.
March Dental uses a digital scanner to capture detailed images of your teeth without traditional messy impressions in many cases. This can be especially helpful for patients with a strong gag reflex or anyone who finds impression trays uncomfortable.
Depending on the situation, a temporary restoration may be placed while the final inlay or onlay is being made. Once it is ready, your dentist will check the fit, bite, and comfort before bonding it securely to the tooth. The restoration is then polished so it feels smooth and natural when you chew.
Caring for Your Inlay or Onlay
Dental inlays and onlays should be cared for just like natural teeth. Brush twice a day, floss daily, and keep up with regular dental exams and professional cleanings. Although the restoration itself cannot decay, the natural tooth around it can still develop cavities or gum problems if plaque builds up.
Avoid chewing ice, biting hard objects, or using your teeth as tools, as these habits can damage both restorations and natural teeth. If you grind or clench your teeth, your dentist may recommend a custom night guard to help protect your inlay, onlay, and surrounding teeth from excessive force.
At March Dental, we check existing restorations during routine exams to make sure they remain secure, comfortable, and properly sealed. If you notice sensitivity, roughness, looseness, or pain when biting, it is best to schedule an appointment so the tooth can be assessed early.
Restoring Strength While Preserving Your Smile
Inlays and onlays can be an excellent middle-ground solution for teeth that need more support than a filling but do not require a full crown. At March Dental, we focus on recommending treatment that supports your oral health, comfort, and long-term function.
If you have a large cavity, cracked filling, broken tooth, or worn restoration, our Kanata dental team can help you understand whether an inlay or onlay is right for you. New patients are welcome, and same-day appointments may be available for urgent concerns such as broken teeth, tooth pain, or lost fillings.
Contact March Dental today to book an appointment and restore your tooth with care that is precise, natural-looking, and designed to last.
