Have you noticed some people have strange marks on their teeth? Many reasons can cause coloured spots or discoloration of the tooth. Some of these issues could be serious. Listed below is everything you need to know about coloured spots on your teeth and how they can be treated.


Strange markings and the reason behind them

Teeth spotting and discoloration can be broadly categorized into four varieties.

Black or dark spots

Unless it is from a pen or marker, black spots on your tooth are a cause of concern. The reasons that could be causing these dark marks may include a cavity, tooth decay, celiac disease, or fluorosis. It could also be a reaction to an antibiotic, injury, tartar deposits, or staining from long-term use of tobacco, tea, coffee, wine, and dark sodas.

White spots

However bright your teeth may be, white spots will stand out. If you notice these scattered over the surface of your teeth, it could be due to demineralization. Highly acidic or sugary food, poor oral care, fluorosis, or excess fluoride content could also lead to white spots on teeth. Enamel Hypoplasia, or Turner’s tooth, is another reason white marks appear on people’s teeth. It is a defect in the thickness and quality of the enamel of the tooth, making it prone to decay.

Brown spots

Pale brown spots are generally a sign of bad oral hygiene. But if they are darker, almost black, the reasons could be the same as those shared for black spots.

Pink spot

Pink spots on teeth are often dangerous as they point toward significant damage to the structure of the teeth. These are caused due to different types of internal or external lesions.


Types of tooth discoloration

There are various types of tooth discoloration. It can be caused by something completely avoidable, like surface stains caused by dark pigments present in tobacco, some types of drinks, and food products. Or it could be a side-effect of some medications, dental trauma, genetic condition, or even age.


Treatment options

Here are a few treatment options that you can take up based on the reason behind the marks and discoloration of your teeth.

Professional dental cleanings and fillings

If your tooth has black spots due to decay, your dentist will need to remove the affected part of your teeth and put in fillings. After this procedure, maintain good oral care. Visiting your dentist for cleanings and fillings maintenance once every six months will help you avoid further dental issues.

Professional teeth whitening

Are you used to drinking tea, coffee, alcohol, or other dark beverages? Then it would help to get professional teeth whitening done at least once a year.

Cosmetic dentistry

There are many cosmetic dentistry procedures like dental bonding, crowns, fluoride treatment, and veneers that can help you fix your dental problems.


Whatever colour the spots or marks on your tooth may look like, it is prudent to consult your dentist immediately to find the exact reason behind them. Based on the diagnosis, you can go ahead with the required treatment. Cleanings and fillings work, professional teeth whitening, and other cosmetic dentistry procedures can help fix the strange discoloration or marks on your teeth.

My family and I have been receiving care from Dr. Ashraf and his amazing team since we first moved to Waterloo in 2002. His assessment skills are spot on, he is gentle and is very skilled at working with anxious\nervous patients. My dental hygienist is Lin who is very knowledgeable, and passionate about her work. She is amazingly gentle yet very,very thorough when it comes to preventative dental care. She is didactic as well, taking the time to teach patients how to use certain equipment as well as addressing gingivitis in pro-active ways. We are in very capable hands.

I have been a patient here for over 2 years now and I've always enjoyed the experience. The staff are professional and have always made me feel comfortable. I recently had a cleaning done by Lynn for the first time and she was amazing! Will continue to visit for my checkups/cleanings.

My family loves Dr Ashraf. We've been through many dentists in many cities and he's by far our favourite one. He's always thorough and professional. His referrals are also of equal high caliber. I went to him for a root canal and a crown. I had many concerns and he addressed them all personally. He even went so far as to redo a root canal for me. Recommend.

I found Ashraf Dentistry a year ago and I absolutely love their dental clinic. Everyone is very kind and thorough. Lin is the best dental hygienist I've ever had! She takes the time to ensure I receive the care I need. Both dentists I've seen have also been very kind and wonderful at making me feel like my teeth are being taken care of. Highly recommend!
