Why are my teeth getting shorter?
Checked and updated for accuracy on 02/03/23
When Glamour magazine ran an article last month about preventative aging & the benefits of wearing a night guard, many became enlightened to one of the sneakiest signs of aging; teeth grinding and as a result, teeth shortening.
The wearing down of teeth is a natural sign of aging. As life goes on, our teeth gradually wear down, become more uneven and more susceptible to yellowing/staining. This can be a slow transformation or a faster one depending on several factors including a person’s genetics and teeth grinding habits.
Causes of the wearing down of teeth
Attrition, abrasion and erosion are all contributors to the shortening of teeth. This can have a less than desirable effect on your smile and self esteem! The shortening of teeth can even effect your bite.
Teeth grinding and clenching can speed up the flattening of teeth. This common subconscious act affects 10% of the population and can also make your teeth more vulnerable to cracking/breakage.
Do shorter teeth make me look older?
The shortening of teeth can cause an aged appearance. The lips sag inward and the distance between the nose and chin shortens. Facial sagging causes a person to show less of their teeth when they smile.
What can I do to prevent teeth shortening?
There is one constantly overlooked anti-aging secret that works to protect your teeth from shortening.
Wear a Dental Night Guard.

Our Skin Is Nothing Without Good Bones, Muscles and Teeth Structure
Sometimes we forget that our skin is just a vessel for our bones and muscles. If a person undergoes changes to the teeth, whether they have them removed (and replace with dentures) or if the teeth have become much shorter over time, it is common to notice sagging skin around the mouth and chin.
Physically, teeth grinding can have some long lasting effects. After years of wearing the teeth down, the face can develop a noticeable sagging appearance that cannot be fixed with anything less than expensive cosmetic work.
The Problem With Short Teeth
It’s no secret that our teeth play a big role in the overall appearance of the face. The wearing down of teeth because of grinding and or clenching is a tell-tale sign of aging.
Simply put, teeth that are too short can absolutely make us look older.
Other notable characteristics that can occur from teeth grinding are an enlarged jaw muscle (protrusion), and stress lines around the mouth.
Check to see if your teeth are too short
Stand in front of a mirror with your lips slightly apart in a relaxed position. If you relax your mouth and just leave it agape slightly, there should be between 1-3mm of tooth exposure.
Do you see a little bit of your front teeth? If you do not, your teeth may be too short. This is not always a result of teeth grinding. This can simply be your natural dental anatomy. If you wish to have your teeth extended you can opt for direct bonding or porcelain veneers.
Some Good News
It’s preventative.
A night guard acts as a preventative to the effects of teeth grinding and teeth aging. Think of it as putting your teeth in a perfectly fitting case each night before bed so that they remain safe and protected against well…yourself.


Simply wearing a night guard at night will prevent your teeth from wearing down. 1 in 10 people grind their teeth at night. A custom made dental guard is far less expensive than restorative cosmetic work. Preserve your teeth & face & prevent teeth flattening the natural way. It’s just as important and routine as putting face moisturizer on at night to prevent dryness and excess wrinkles.

How to keep your night guard clean and bacteria free
As you probably well know, wet and dark places are a great breeding ground for bacteria. Your night guard can go from a nice clear to yellow and smelly in a matter of months. Make sure you store your night guard in its original case.
Clean with a soft toothbrush and a little toothpaste. Rinse thoroughly and store dry. Dry is the secret to a clean long lasting night guard. You do not want water sitting in your guard night after night. Additionally, Efferdent makes a really great denture/retainer cleaner you can use once a week to preserve the life of your guard.

Other reasons to wear a dental night guard at night
Wearing a night guard has so many benefits! It prevents cracking and breaking of natural teeth and dental work. It will protect a new set of porcelain veneers, bonding, crowns & bridge work. If you wake up in the morning with jaw soreness, tension or pain this can be a sign that you’re either clenching your teeth at night or grinding them together. Overtime, this will lead to teeth flattening.
