When Do You Need an Inlay or Onlay?

When Do You Need an Inlay or Onlay?

Apr 09, 2025

You may have tooth decay and damage over time. Therefore, even with constant brushing and flossing, cavities and cracks may still appear. If a crown seems excessive and a standard filling isn’t sufficient, there are several choices available.You might wish to consider an inlay or onlay in Bolton if you are considering options for minor tooth damage. They keep as much of your tooth’s healthy structure as possible while giving it back strength and structure.

In this guide, we explain inlays and onlays and how you can know whether they are the right option for you.

What Are Inlays and Onlays?

Custom restorations called inlays or onlays are used to repair damaged or diseased teeth. They may be composed of gold, composite resin, or porcelain. The primary distinctions are seen in the region of the tooth surface that they cover:

  • Inlays lie fittingly on the grooves of the tooth, as would its filling.
  • Onlays cover up one or more raised portions, more commonly known as cusps, at times sweeping over the edges.

They are stronger than fillings yet kinder to the tooth structure than crowns; hence, they are ideal for moderate cases and more conservative than crowns, making them a great option for moderate cases.

What Distinguishes Crowns and Fillings from Inlays and Onlays?

Procedure time One visit (usually) Two visits Two visits Two visits
Material durability Lower High High Very high

What Indicates the Need for an Onlay or Inlay?

The best dental surgery for your situation may not always be obvious to you. However, some indicators show when an inlay or onlay would be the best option. 

Below are a few signs you need an inlay or onlay:

  • Although there is some decay in your tooth, it is not severe enough to require a crown.
  • Your tooth is broken or cracked and requires further support. 
  • Old fillings are failing or breaking
  • You want a more durable and aesthetic solution

It’s critical to schedule an examination with your dentist if you have any of these symptoms.

Benefits of Inlays and Onlays

Choosing inlays or onlays has several advantages over traditional options:

  • Durable: They can endure for at least 15 years with the right maintenance
  • Improved fit: They are manufactured to order to precisely fit the injured region.
  • Tooth preservation: They keep more of your natural tooth intact compared to crowns.
  • Aesthetics: Tooth-coloured materials blend well with your smile.
  • Strong bond: They are cemented to the tooth, providing extra strength and support.

For many dental patients, inlays and onlays are a dependable and alluring option because of these advantages.

What Is the Procedure Like?

The process usually takes two visits. Here’s what to expect:

Visit 1:

  • The impacted tooth will be examined and cleaned by your dentist. 
  • The dentist will take a physical or digital impression of your tooth.
  • A temporary filling may be placed.

Visit 2:

  • A custom inlay or onlay is placed and fixed.
  • It is then permanently bonded to your tooth.

Some dental clinics offer same-day inlays and onlays using advanced digital scanning and milling machines.

Caring for Your Inlay or Onlay

Maintaining your dental restoration is simple:

  • Brush at least twice a day
  • Floss daily to remove debris
  • Visit your dentist regularly for cleanings and exams

Good oral hygiene and routine dental care will help your inlay or onlay last for many years.

When Should You Visit a Dentist?

Don’t delay if you have noticeable tooth cracks, tooth sensitivity, or pain when you chew. Your tooth can be saved and additional harm can be avoided with early treatment.

Ignoring these issues may result in needing more invasive treatments later on, like a full crown or even extraction.

Wrapping Up!

Inlays and onlays are smart, long-lasting solutions for teeth that need more than a filling but less than a crown. If you’re experiencing any symptoms or believe your tooth may need extra support, schedule a consultation.
