Dental Assessment for Inlays and Onlays

Dental Assessment for Inlays and Onlays

Finding out that a tooth has been damaged doesn’t necessarily mean the same treatment is right for everyone. The amount of healthy tooth remaining, where the damage is located, and your overall oral health can all influence the options that may be suitable.

For some people, a filling may no longer give the tooth enough support, while a full crown might remove more tooth structure than necessary. This is where inlays and onlays may come into the conversation for patients in Lalor and across Melbourne, depending on the condition of the tooth.

 At Supreme Dental Lalor, we may assess the affected tooth and explain whether an inlay or onlay may be appropriate. We may also discuss how it compares with other treatment options, along with the possible benefits and considerations, based on your individual oral health needs.

What Are Inlays and Onlays?

Inlays and onlays are custom-made restorations that may be used to repair part of a tooth affected by decay, damage or wear. They are designed to fit the prepared area and may be made from materials such as porcelain or composite resin.

If you’re exploring inlays and onlays in Lalor and across Melbourne, understanding the difference between these restorations may help you know what questions to ask during your appointment.

Although they have a similar purpose, inlays and onlays cover different areas of the tooth.

Inlays

An inlay generally sits within the grooves of a tooth, between the raised edges called cusps. It may be considered when the damaged area is contained within the central part of the tooth.

Onlays

An onlay covers a larger area and may extend over one or more cusps. It could be discussed when damage or wear affects more of the tooth’s chewing surface.

The choice between an inlay, onlay or another restoration depends on the individual tooth and its condition.

When Might an Inlay or Onlay Be Discussed?

An inlay or onlay could sometimes be considered where a tooth has experienced more extensive damage than a conventional filling may be able to restore appropriately.

Some situations that may lead to a discussion about these restorations include:

  • Decay affecting a significant part of a tooth
  • A chipped or cracked tooth
  • A large or worn filling
  • Damage to the chewing surface
  • Tooth wear
  • Discomfort when biting or chewing
  • Food repeatedly becoming trapped around one tooth

These signs do not necessarily mean an inlay or onlay is required. An examination is needed to understand the cause of the problem and determine which options, if any, may be appropriate.

Inlay or Onlay: Which One Could Be Considered?

Although both restorations are designed to repair part of a tooth, their coverage differs.

An inlay may be considered when the affected area is contained within the cusps of the tooth. An onlay may be discussed when the damage or wear extends further and involves one or more cusps.

The choice is not based on symptoms alone. We may consider the location and extent of the damage, the remaining natural tooth structure and the overall condition of the tooth.

Could a Filling Still Be an Option?

A filling may be suitable for some areas of decay or relatively smaller defects. However, when a larger portion of the tooth has been affected, a dentist may need to consider whether a filling is appropriate for the particular situation.

An inlay or onlay could sometimes be discussed where more extensive restoration is needed but a crown may not necessarily be required.

There is no single restoration that suits every damaged tooth, which is why an individual assessment is important.

What Happens During Your Assessment?

Before recommending any restorative approach, we may examine the affected tooth and surrounding areas. Depending on your symptoms and what we find, dental X-rays or other assessments might also be considered.

We may look at:

  • The extent and location of the damage
  • How much healthy tooth structure remains
  • The condition of an existing filling, if applicable
  • Your bite and chewing function
  • Any discomfort or sensitivity you have noticed

We’ll then explain the options that could be relevant and give you an opportunity to ask questions.

What Does the Inlay or Onlay Procedure Involve?

The process can vary depending on the tooth and restoration. In some cases, treatment may involve two appointments.

Preparing the Tooth

We may first remove decay or damaged tooth structure where clinically appropriate. An impression or digital scan could then be taken to help create a restoration that matches the prepared area.

A temporary restoration might be placed while the custom inlay or onlay is being made.

Fitting the Restoration

At the following appointment, we may remove the temporary material and check the fit of the completed restoration.

We’ll also assess your bite and may make small adjustments if needed. If the fit is appropriate, the inlay or onlay may then be bonded to the tooth.

The exact process and number of appointments can differ between patients.

What Are Inlays and Onlays Made From?

Inlays and onlays may be made from different materials, with porcelain and composite resin among the options that could be considered.

The material chosen may depend on several factors, including the location of the tooth, the size of the restoration, the amount of remaining tooth structure and your individual circumstances.

We can talk through the available options with you before treatment so you understand what may be involved.

What Might You Notice After the Restoration?

It can take a little time to become accustomed to a newly restored tooth. You might notice that the tooth feels different initially, and some people may experience temporary sensitivity.

If you develop ongoing discomfort, notice a significant change in your bite or feel that the restoration is loose or damaged, you could contact us for an assessment.

A dentist can then determine what may be causing the change and whether anything needs attention.

How Long Could an Inlay or Onlay Remain Functional?

There is no guaranteed timeframe for how long an inlay or onlay will last. Its longevity can vary depending on several factors, such as:

  • The material used
  • The condition of the tooth
  • The amount of natural tooth structure remaining
  • Oral hygiene
  • Eating habits
  • Teeth grinding or clenching
  • The forces placed on the tooth
  • Ongoing dental care

An inlay or onlay may remain functional for a number of years, although this can differ from person to person.

Regular dental appointments could allow us to check the restoration and the tooth around it and identify any changes that may need attention.

Looking After Your Restored Tooth

An inlay or onlay still needs everyday care. You can continue to look after the restored tooth as part of your normal oral hygiene routine.

This may include:

  • Brushing twice a day with fluoride toothpaste
  • Cleaning between your teeth daily
  • Limiting frequent sugary foods and drinks
  • Avoiding biting down on very hard objects such as ice
  • Attending regular dental check-ups

If you grind or clench your teeth, mention this during your appointment. It could be relevant when we assess your tooth and discuss restorative options

Have Questions About Inlays and Onlays?

A damaged or heavily restored tooth can leave you unsure about what comes next. A dental assessment can help identify the condition of the tooth and clarify which restorative options are relevant to your circumstances.

If you’re in Lalor or elsewhere in Melbourne, you may contact Supreme Dental Lalor to arrange an assessment and discuss whether an inlay or onlay is appropriate for your tooth.
