Why Is My Tooth Gray?

You may have noticed something different in the mirror one morning. Your teeth are turning gray. 

This usually doesn’t happen all at once but rather gradually over time. The team at Northside Dental Clinic in Springfield, MO, explains what causes gray teeth and how to fix the issue. 

Tooth Decay

The number one cause of a gray tooth is decay. Essentially, decay cuts off blood flow, turning teeth gray.

Don’t panic if you suspect tooth decay. Your teeth can survive without blood flow, as adult teeth only need the blood vessels as they develop. However, you may need to take care of the decay affecting part of your gray tooth. The team at Northside Dental Clinic can help you create an oral hygiene regimen to prevent further tooth decay.


Your teeth may turn gray simply because you’re getting older. 

As you age, your body gradually changes its biochemical processes. This may alter the way your tooth receives nutrients or how the blood flows to the tooth. You may see gray-blue teeth in the mirror as you age.


Anything that cuts off blood flow to your tooth can cause it to turn gray, including tooth trauma. 

Tooth trauma comes in many forms, but common causes include accidents or sports injuries. For example, you might chip a tooth when you accidentally hit your head on an object.


Tetracycline is an antibiotic drug that fights infections. If a doctor prescribes tetracycline, a gray tooth is one of the side effects that may happen in children. 

This discoloration is due to the drug getting inside the developing adult teeth before they come in, turning the enamel a shade of gray.

How Do I Get Rid of Gray Teeth?

If your gray teeth aren’t caused by tooth decay, you typically shouldn’t worry about the color. However, we all want to have brighter, healthier-looking smiles. Several whitening options are available.

Professional Whitening

Professional whitening is highly effective in whitening gray teeth. A skilled dentist uses advanced techniques to brighten your smile safely. The process usually takes about an hour and can lighten teeth several shades in just one visit. It’s a fast and convenient option for achieving a brighter, more confident smile.

Whitening Toothpaste

Whitening toothpaste can be part of your daily routine to help gradually remove surface stains and lighten the appearance of gray teeth. Look for toothpaste containing gentle abrasives and whitening agents. While whitening toothpaste can help maintain the brightness of your smile, it may take longer to see noticeable results compared to professional whitening treatments.

At-Home Kits 

Northside Dental Clinic offers custom at-home bleaching kits. These kits include custom-fitted trays and professional-strength whitening gel. Your dentist will provide instructions on how to use the kit safely and effectively. At-home whitening provides convenience while still achieving professional-level results.
