Inlays and onlays

At Harley Private Dental, inlays and onlays are carefully planned and crafted to achieve a precise fit and natural-looking result.

What are inlays and onlays?

Inlays and onlays are indirect restorations, meaning they are made outside of the mouth and then bonded to the tooth. They are typically created from tooth-coloured materials designed to blend seamlessly with natural teeth.

• Inlays fit within the grooves of a tooth and do not extend over the biting surface.
• Onlays cover a larger area and extend over one or more cusps (the raised points of a tooth).

Both options provide a strong, durable restoration while maintaining a conservative approach to treatment.

What is the difference between an inlay and an onlay?

The difference lies in how much of the tooth is being restored:

• Inlay:
  Used when damage or decay is confined within the central part of the tooth. It sits neatly inside the tooth structure.
• Onlay:
  Used when damage extends to the biting surface or cusps of the tooth. It provides additional coverage and reinforcement.

Your dentist will recommend the most appropriate option based on the condition of the tooth.

When might inlays or onlays be recommended?

Inlays and onlays may be recommended when:

• A tooth has moderate decay or damage
• A traditional filling would not provide enough strength
• The tooth does not require a full crown
• An existing filling has failed or fractured
• Long-term durability and precision are important

They are often considered a middle ground between a filling and a crown.

Who is suitable for inlays and onlays?

Inlays and onlays may be suitable if you:

• Have a tooth with moderate damage or decay
• Have sufficient healthy tooth structure remaining
• Want a strong, long-lasting restoration
• Maintain good oral hygiene

Suitability depends on the size of the restoration needed, bite forces, and overall oral health. A consultation is required to assess the tooth properly.

What does the treatment involve?

Treatment for inlays and onlays is usually completed over two appointments:

1. Assessment and preparation
   The tooth is examined and prepared, and impressions or digital scans are taken. A temporary restoration may be placed to protect the tooth.
2. Fitting the inlay or onlay
   The custom-made restoration is bonded securely to the tooth and adjusted to ensure comfort, function, and a natural appearance.

The process is carefully planned to ensure accuracy and comfort throughout.

What results can I expect?

Inlays and onlays are designed to:

• Restore the strength and function of the tooth
• Blend naturally with surrounding teeth
• Provide a precise, long-lasting fit
• Help protect the tooth from further damage

When properly cared for, they can last many years and perform similarly to natural tooth structure.

Caring for inlays and onlays

Caring for an inlay or onlay is similar to caring for natural teeth:

• Brush twice daily
• Clean between teeth regularly
• Attend routine dental check-ups and hygiene appointments
• Avoid habits such as biting hard objects

Regular reviews allow your dentist to monitor the restoration over time.

Are inlays or onlays right for me?
