Do Missing Teeth Need to Be Replaced? What to Know

I Already Removed the Tooth. Do I Really Need to Replace It? 

Patients Ask Series: Part 1

Hey Smile Squad!😁

Not every missing tooth needs to be replaced. Your dentist will consider which tooth was removed and examine how the gap affects the surrounding teeth. This assessment will help your dentist decide if tooth replacement is recommended.

At the clinic, I often hear patients ask why they need to replace a tooth that has already been removed. The pain has stopped, and they can finally sleep again. That relief can make tooth replacement seem unnecessary because the extraction has solved the problem they could feel.

Tooth extraction may remove the immediate source of pain or infection, but changes can still develop around the gap even when the area feels fine.

 What Happens If a Missing Tooth Is Not Replaced?

Nearby Teeth May Move Into the Gap

If a missing tooth is not replaced, the teeth beside the gap may slowly move towards the empty space. Think of your teeth as a row of books standing closely together on a shelf. Remove one book from the middle and the books beside it now have room to lean. Teeth move much more slowly because their roots hold them firmly inside your jawbone, but your nearby teeth may still tilt into the gap over time. The tooth above or below the gap may also move because it no longer meets another tooth when you bite.

Can a Missing Tooth Make Chewing Difficult?

Yes, a missing tooth can make chewing more difficult, but the effect depends on where the gap is. Front teeth help you bite into foods such as bread, meat and fruit, while back teeth break food into smaller pieces before you swallow. Losing one of these teeth may make eating less comfortable or effective.

Some people begin chewing more on the other side of their mouth after losing a back tooth because it feels easier. This does not happen to everyone, but difficulty eating is one reason your dentist may recommend replacing a missing tooth.

 What Happens to Your Jawbone After a Tooth Is Removed?

After a tooth is removed, the bone that once held its root naturally begins to change. The root is no longer there to pass pressure from biting and chewing into that part of the jawbone, so the bone may gradually become smaller.

A smaller amount of jawbone can affect the tooth replacement options available to you. For example, a dental implant needs enough bone for support. If your dentist finds that there is not enough, you may need an additional treatment called bone grafting to help build up the area. Guy’s and St Thomas’ NHS Foundation Trust explains how bone grafting can increase the amount of bone available⁠ for an implant.

Can a Missing Tooth Make Cleaning More Difficult?

Changes around a missing tooth can sometimes make cleaning more difficult. Food may collect around the gap, especially if a nearby tooth has tilted towards it. This can allow more plaque, the sticky layer of germs that forms on teeth, to build up in the area.

Cleaning around your tooth gap remains important even when the area does not hurt. Careful brushing and cleaning between your teeth can help protect your nearby teeth and gums, while regular dental check-ups allow your dentist to notice any changes early.

Can a Missing Tooth Affect Your Confidence?

A visible gap can affect your confidence, especially when it shows as you smile or talk. When several teeth are missing, the lips and cheeks may have less support, which can change your facial appearance. This type of change is less likely to be noticeable after losing only one tooth.

Some people feel uncomfortable about a missing tooth, while others are not bothered by it. You can discuss how the gap makes you feel with your dentist when considering tooth replacement.

Do All Missing Teeth Need to Be Replaced?

No, not all missing teeth need to be replaced. Your dentist may advise leaving a gap if it does not affect how you eat and is unlikely to cause problems for your remaining teeth. They will also look at where the gap is and how your teeth meet when you bite.

Wisdom teeth are a common example because they are usually not replaced after removal. Some gaps left by other teeth may also be left alone if you have enough natural teeth to eat comfortably. 

What Are the Options for Replacing a Missing Tooth?

A missing tooth can be replaced with a dental implant, bridge or denture. The option your dentist recommends will depend on the position of the gap, the condition of your remaining teeth and the amount of bone available.

You can read how dental implants replace missing teeth in Part 3 of this series. Bridges and dentures will be explained in separate articles.

💙 Mariam’s Wrap

If you want to know how the gap left by a missing tooth could affect your mouth, ask your dentist to check it at your next appointment. You do not have to decide on tooth replacement immediately. Your dentist can explain what is happening around the gap and recommend the next step.
