Losing a tooth can happen for many reasons, including tooth decay, gum disease, injury, or an extraction. While a missing tooth may not seem like an urgent problem if it does not cause pain, leaving the space untreated can affect more than just your smile.
So, what happens if you don’t replace a missing tooth? Over time, the surrounding teeth can shift, your bite can change, and the jawbone in the area may gradually lose density.
The good news is that there are several options for replacing missing teeth. A dentist can assess your oral health and recommend the most appropriate solution for your situation.
What Happens When You Leave a Missing Tooth Untreated?
A missing tooth creates an empty space in your mouth. Your teeth, gums, jawbone, and bite all work together, so losing one tooth can gradually affect the surrounding structures.
Here are some of the common effects of leaving a missing tooth untreated.
1. Your Other Teeth May Shift
Your teeth naturally support and interact with one another. When one tooth is missing, the teeth next to the gap may begin to move into the empty space.
This movement can:
- Create gaps between teeth
- Cause teeth to tilt or rotate
- Make cleaning between teeth more difficult
- Affect the alignment of your bite
Over time, these changes can make your teeth more difficult to keep clean and may affect your overall oral health.
If your teeth have already started shifting, your dentist can discuss whether orthodontic treatment may be appropriate. You can also learn more about ways to straighten teeth without braces.
2. Your Bite Can Change
Your upper and lower teeth are designed to work together when you chew. A missing tooth can change how pressure is distributed when you bite.
You may start chewing more on one side of your mouth to compensate for the missing tooth. This can put additional stress on some of your remaining teeth.
A changed bite may also affect how comfortable your jaw feels when eating or speaking.
3. You May Experience Jawbone Loss
One of the most important effects of tooth loss happens below the gumline.
The roots of your teeth help stimulate the jawbone. When a tooth is lost, that stimulation is no longer present in the same way. Over time, the bone surrounding the missing tooth can gradually shrink.
This is known as bone resorption.
Jawbone loss can affect the shape and support of the area around the missing tooth. It can also become an important consideration when planning certain tooth-replacement options.
4. Eating Certain Foods May Become More Difficult
Even one missing tooth can affect how you chew.
Depending on where the tooth was located, you may find some foods harder to bite or chew comfortably. You may also develop the habit of using the opposite side of your mouth.
Replacing the missing tooth can help restore more balanced chewing function.
5. Your Remaining Teeth May Experience More Stress
Your remaining teeth may have to do more work when one or more teeth are missing.
This can place additional pressure on the teeth that remain, particularly if your bite has changed.
Protecting your remaining natural teeth is an important part of managing tooth loss. Regular dental exams can help your dentist monitor changes and identify problems early. If you’re unsure why routine dental examinations are important, see our guide on why you need a dental exam.
6. Cleaning Around Your Teeth Can Become More Difficult
When teeth shift into the space left by a missing tooth, new spaces and angles can develop.
These areas may be harder to brush and floss effectively. Difficulty cleaning around the teeth can allow plaque and bacteria to build up, potentially increasing the risk of gum problems and tooth decay.
Good daily oral hygiene remains important whether or not you have missing teeth. Our daily steps for healthy teeth and gums can help you maintain your oral health at home.
7. A Missing Tooth Can Affect Your Smile
A missing front tooth is usually more noticeable, but even a missing back tooth can eventually affect the appearance of your smile if surrounding teeth move.
Tooth loss can also affect the shape of the gum and bone around the missing tooth.
For many people, replacing a missing tooth is therefore about both function and appearance.
How Long Can You Leave a Missing Tooth?
There is no single timeframe that applies to everyone.
Some people may have a missing tooth for years without experiencing obvious symptoms, while others may notice changes sooner. The location of the missing tooth, your bite, gum health, bone health, and the condition of your remaining teeth can all make a difference.
The absence of pain does not necessarily mean that there is no problem.
If you have recently lost a tooth or have had one removed, it is a good idea to discuss your options with a dentist rather than simply leaving the space untreated.
Do All Missing Teeth Need to Be Replaced?
Not necessarily.
The best approach depends on which tooth is missing, why it was lost, your overall oral health, and how the missing tooth affects your bite and function.
Your dentist may recommend monitoring the area in some situations. In other cases, replacing the tooth may help protect your remaining teeth and restore chewing function.
A dental examination can help determine whether replacement is recommended in your particular case.
What Are the Options for Replacing a Missing Tooth?
There are several ways to replace a missing tooth. Your dentist will consider factors such as your oral health, jawbone condition, the number of missing teeth, and your preferences.
Dental Implants
A dental implant is a long-term tooth-replacement option that uses an implant placed in the jawbone to support a replacement tooth.
Dental implants can help restore both the appearance and function of a missing tooth.
If you’re considering this option, read more about the benefits of dental implants.
You can also learn about the different stages involved in treatment in our guide to the dental implant process.
Dental Bridges
A dental bridge can replace a missing tooth by using the neighbouring teeth to support a replacement tooth.
Bridges can provide a fixed option for restoring the gap, depending on your individual situation.
Dentures
For people who are missing several teeth or all of their teeth, removable partial or complete dentures may be an option.
Your dentist can explain which type of tooth replacement is suitable based on your needs.
Is a Dental Implant Always the Best Option for a Missing Tooth?
Dental implants can be an excellent option for many patients, but they are not automatically the right choice for everyone.
Your dentist needs to evaluate factors such as:
- The health of your gums
- The condition and amount of jawbone
- Your overall oral health
- The location of the missing tooth
- Your bite
- Your medical and dental history

Frequently Asked Questions About Missing Teeth
What happens if you don’t replace a missing tooth?
A missing tooth can cause neighbouring teeth to shift, change your bite, make chewing more difficult, and contribute to gradual jawbone loss. The effects vary depending on the location of the missing tooth and your overall oral health.
Can a missing tooth cause other teeth to move?
Yes. When a tooth is missing, nearby teeth may gradually move or tilt into the empty space. This can affect tooth alignment and your bite.
Does a missing tooth cause bone loss?
It can. When a tooth root is no longer present to stimulate the surrounding jawbone, the bone in that area may gradually decrease in volume.
Is it okay to leave a missing tooth alone?
It depends on the individual situation. Some missing teeth may be monitored, while others should be replaced to help maintain chewing function, tooth alignment, and oral health. A dental examination can help determine the best approach.
What is the best way to replace one missing tooth?
There is no single solution that is best for everyone. Dental implants, bridges, and other options may be considered depending on your oral health, bone condition, bite, and personal needs.
Can a dentist replace a tooth years after it was lost?
In many cases, tooth replacement may still be possible years after tooth loss. However, changes to the jawbone and surrounding teeth may affect which treatment options are available. Your dentist can evaluate the area and discuss your options.
Don’t Ignore a Missing Tooth
A missing tooth may not hurt, but that does not mean it should always be ignored. Over time, tooth movement, changes to your bite, difficulty chewing, and jawbone loss can affect your oral health.
If you have a missing tooth, an examination with a dentist can help you understand whether replacement is recommended and which option may be right for you.
If you’re in Aurora, Ontario, Aurora Family Dentistry can assess your smile and discuss appropriate tooth-replacement options based on your individual needs.
Key Takeaway
A missing tooth can affect more than your smile. Leaving the space untreated may allow surrounding teeth to shift, change your bite, affect chewing, and contribute to jawbone loss. Getting professional advice early can help you understand your options and protect your remaining teeth.
