Inlays and onlays are custom-made restorations used to repair teeth with moderate decay, cracks, or structural loss — typically in the back molars and premolars.
Inlays fit within the cusps (the raised points) of the tooth.
Onlays extend over one or more cusps, covering a larger surface area.
Unlike traditional fillings that are placed directly into the cavity during a single visit, inlays and onlays are indirect restorations that are fabricated in a dental laboratory from materials such as porcelain, composite resin, or gold and then bonded securely to the tooth.
They offer a strong, stable, and more conservative alternative to full dental crowns.
Inlays and onlays are ideal when:
A cavity is too large for a traditional filling
The tooth is weakened but still has enough structure to avoid a crown
There’s mild to moderate damage due to trauma, decay, or grinding
You want a more durable, longer-lasting restoration than a filling
You seek a more aesthetic solution that mimics the natural tooth appearance
At York House Dental Practice, we always aim to preserve as much natural tooth structure as possible, making inlays and onlays an excellent choice in many cases.
The process of receiving an inlay or onlay typically involves two appointments:
We begin with a thorough clinical examination and X-rays to determine the extent of the damage.
The affected tooth is gently cleaned and prepared by removing decayed or weakened tissue.
We take precise digital or traditional impressions of the tooth to ensure your restoration is custom-fitted.
A temporary filling or cover may be placed to protect the tooth while your permanent restoration is fabricated in a dental lab.
Once your inlay or onlay is ready (usually within 1–2 weeks), we remove the temporary filling.
The new restoration is tried in to assess the fit, bite, and colour match.
It is then bonded permanently to the tooth using strong adhesive cement.
We polish and fine-tune the restoration to ensure a comfortable and natural feel.
The result is a long-lasting, discreet, and functional restoration that restores both strength and appearance.
Stronger and more durable than traditional fillings
Preserve more natural tooth structure than crowns
Aesthetic and natural-looking, especially when using tooth-coloured materials
Precise fit for better function and comfort
Resistant to wear and staining, especially porcelain options
Reduce the risk of further decay or fracture
Custom-designed for long-term performance
With proper care, inlays and onlays can last 10–20 years or more, offering a reliable solution for restoring tooth integrity.
Following your inlay or onlay treatment, caring for your restoration is similar to caring for your natural teeth:
Brush twice daily with fluoride toothpaste to maintain healthy enamel and prevent further decay.
Floss daily to remove plaque and debris from between teeth and around the restoration.
Avoid biting hard objects like ice, pens, or fingernails that may damage the restoration.
Limit highly sticky foods that could dislodge or wear down the inlay or onlay.
Attend regular dental check-ups and professional cleanings at York House Dental Practice to ensure the restoration is holding well.
If you grind your teeth at night, a custom nightguard may be recommended to prevent damage.
You may experience mild sensitivity for a few days, which typically subsides. If discomfort persists, we’ll gladly adjust the restoration for you.
You may be a good candidate for inlays or onlays if:
You have a large filling that needs replacement
You have mild to moderate tooth damage not requiring a crown
You want a more natural-looking, long-lasting alternative to amalgam fillings
You’re seeking a conservative restoration that preserves healthy tooth tissue
