Why Is Your Tooth Turning Black? Causes, Prevention, and Treatments
Noticing a black spot on your tooth or realising that a tooth is turning black can be worrying. While a black tooth isn’t something you should ignore, it doesn’t always indicate a serious problem. Understanding what causes these black marks or spots on your teeth can help you address the issue and get the right treatment promptly.
In this blog, we’ll explain why teeth can turn black, what the common causes are, and how you can prevent and treat these issues. We’ll also answer some frequently asked questions to provide more clarity.
What Causes a Tooth to Turn Black?
A black tooth or black spot on a tooth can happen for several reasons. Let’s look at some of the most common causes:
1. Tooth decay (Cavities)
One of the most frequent causes of a black tooth is tooth decay. Cavities can start as small white or brown spots but, if left untreated, can turn black as the decay worsens. This happens because bacteria break down your tooth enamel, and as the decay reaches the inner layers of the tooth, it can become darker.
2. Staining from food, drink, or tobacco
Certain foods and drinks, such as coffee, tea, red wine, and berries, can cause staining over time. Smoking or using tobacco products can also lead to a black mark on your tooth. This type of staining often affects the surface and can sometimes be removed with professional cleaning.
3. Trauma or injury to the tooth
An injury to your tooth, such as a knock or fall, can damage the nerve inside. When the nerve dies, the tooth can discolour, sometimes turning grey or black. This is known as pulp necrosis, and it often requires a root canal treatment to resolve.
4. Tartar build-up
Tartar (hardened plaque) can sometimes appear as a black mark on the tooth, especially if it accumulates near the gumline. This build-up is caused by poor oral hygiene and can’t be removed with regular brushing. A dental professional can clean tartar off your teeth during a routine visit.
5. Dental fillings or restorations
Older fillings, particularly those made from amalgam (a silver-coloured material), can sometimes cause the surrounding tooth structure to appear black. This is due to staining from the metal within the filling.
How to Prevent Your Teeth from Turning Black
Prevention is always better than cure. Here are some practical tips to help you avoid black teeth or black spots:
- Brush twice a day: Use fluoride toothpaste and brush for at least two minutes each time.
- Floss daily: This helps remove plaque and food particles between your teeth.
- Regular dental check-ups: Visit your dentist at least twice a year for professional cleanings and examinations.
- Reduce sugary foods and drinks: Limit your intake of sweets and fizzy drinks, which can contribute to tooth decay.
- Avoid smoking: Tobacco is a major cause of staining and can also lead to gum disease and other oral health issues.
- Use a straw for staining drinks: If you drink coffee, tea, or red wine, using a straw can reduce direct contact with your teeth.
Why It’s Important to Tell Your Dentist If You Vape
Honesty is always the best policy when it comes to dental care. Letting your dentist know that you vape allows them to give you the best care and advice tailored to your needs. Your dentist can recommend strategies to minimise the impact of vaping on your oral health, such as increasing hydration, using fluoride treatments, or scheduling more frequent cleanings to counteract plaque build-up.
Being open about vaping also means that your dentist can keep an eye out for specific issues related to vaping, such as early signs of gum disease or oral infections, and treat them before they become more serious problems.
In conclusion
Seeing your tooth turning black or finding a black spot can be alarming, but it’s often a problem that can be resolved with the right care. Whether the issue is due to decay, staining, or injury, your dentist can help you address it and keep your smile healthy.
Remember, maintaining good oral hygiene and attending regular dental check-ups are the best ways to prevent black teeth and other dental issues. Don’t hesitate to book an appointment if you notice any changes in your teeth!
