Have you looked in the mirror and noticed that your teeth seem longer than they used to? It may not be that your teeth have actually grown. In many cases, the change happens because the gum tissue around the teeth has moved upward or worn away.
This is known as gum recession. Besides changing the appearance of your teeth, recession can expose the roots underneath the gums. That can make certain teeth more sensitive and leave areas that are harder to keep clean.
Why Do Teeth Start Looking Longer?
Your gums normally cover and protect the lower portion of each tooth. When that tissue recedes, more of the tooth becomes visible.
Several things can contribute to this change.
Gum disease
Bacteria and inflammation can damage the tissues that support your teeth. As periodontal disease progresses, the gums may pull away from the teeth and supporting bone can also be lost.
Bleeding when brushing, swollen gums, persistent bad breath, or loose teeth can be warning signs that the problem goes beyond appearance.
Brushing too hard
More pressure does not necessarily mean cleaner teeth. Aggressive brushing, particularly with a hard bristled toothbrush, can gradually irritate or wear away gum tissue.
If recession is concentrated around a few teeth, your brushing technique may be one factor worth discussing with a dental professional.
Naturally thin gums
Some people have thinner gum tissue and are more prone to recession. You can have good brushing and flossing habits and still develop visible changes around certain teeth.
Grinding or clenching
Repeated pressure from grinding or clenching can place additional stress on the teeth and surrounding tissues. If you also wake up with jaw soreness or notice worn tooth surfaces, mention it during an examination.
Look at More Than Just Your Smile
The appearance of your teeth can provide an early clue, but other changes can tell you more.
Watch for:
- A tooth looking noticeably longer than the one beside it
- A notch or indentation near the gumline
- Increased sensitivity to cold drinks or hot foods
- Roots that appear yellowish compared with the tooth crown
- Bleeding or swollen gums
- Food getting trapped around the gumline
- Persistent bad breath
- Teeth that feel loose or different when you bite
An exposed root can also be more vulnerable to sensitivity and decay because it does not have the same enamel protection as the crown.
Can Receding Gums Grow Back?
Unfortunately, gum tissue that has already been lost generally does not grow back on its own.
That does not mean every case requires surgery. The appropriate treatment depends on why the recession developed, how much tissue has been lost, and whether there is active periodontal disease.
A periodontal evaluation can determine whether the priority is controlling inflammation, changing an oral hygiene habit, monitoring the area, or restoring lost tissue.
For more advanced recession, surgical treatment for receding gums may include procedures such as gum grafting that cover exposed roots and help protect vulnerable areas.
When Should You Have It Checked?
Do not wait for pain before getting noticeable gum recession evaluated. Gum problems can progress without causing significant discomfort.
It is particularly important to have an examination if your teeth are continuing to look longer, your gums bleed regularly, roots are visibly exposed, or you have developed new sensitivity.
An oral health specialist can examine the gumline, measure areas of recession, assess the supporting tissues, and determine whether the change is stable or progressing.
If you need a dentist who can evaluate changes in your gums, getting the area examined can help distinguish normal variation from a problem that needs treatment.
A Small Change Can Be Worth Investigating
Teeth that suddenly look longer are not something you should automatically dismiss as an appearance issue. The change may be mild, but it can also be a visible sign that the protective gum tissue has moved away from the tooth.
If you are in Palmdale and have noticed receding gums or exposed roots, you can find the Palmdale office on Google Maps before your visit.
Know What Is Changing Before It Gets Worse
Synergy Endodontics provides periodontal care in Palmdale for patients experiencing gum recession, exposed roots, and other changes affecting the tissues around their teeth. If your teeth look longer than they used to, schedule an appointment to find out what is causing the change and whether treatment can help protect the affected area.
Frequently Asked Questions
Do teeth actually grow longer with age?
No. Adult teeth do not normally grow longer. They can appear longer when gum tissue recedes and exposes more of the tooth.
Is gum recession always caused by gum disease?
No. Gum recession can also be associated with brushing habits, naturally thin gum tissue, grinding, tooth positioning, and other factors.
Can receding gums cause sensitive teeth?
Yes. Recession can expose root surfaces that are more sensitive to temperature and touch.
Should I worry if only one tooth looks longer?
It is worth having it checked, particularly if the change is new or accompanied by sensitivity, bleeding, or a visible change in the gumline. A localized problem can affect one tooth before changes become noticeable elsewhere.
