White Spots On Teeth: Why Do I Have Them and How To Get Rid Of Them?

Written by Eshna Das

White spots on teeth is something that you may have noticed when talking to someone or while inspecting our own teeth in the mirror. Have you ever wondered why they appear and how to get rid of these white dots on teeth? Studies show that one of the factors responsible for the development of white spots is too much exposure to fluoride (1). The American Dental Association suggests that engaging in simple, everyday practices such as brushing your teeth twice a day can prevent white spots from developing (2).

Why Do I Have White Spots On My Teeth?

White spots, also known as white spot lesions develop due to loss of minerals on the enamel, which lead to our teeth looking discolored and mess with our aesthetics. Having these white spots can make you feel conscious when you talk or smile (3). However, worry not because dentists and orthodontists have a host of procedures that help remove these white spots. But before we go to the treatment options, let us first understand what causes white spots on teeth. The following are factors that are known to contribute to the development of white spots on your teeth.

  • Dental Fluorosis

Dental fluorosis occurs when you develop white stains on your teeth due to constant exposure to fluoride over a long period of time (4). This is a condition that only develops in children and is not found in adults (5). You can recognize if your kids have dental fluorosis by checking for white streaks on the teeth. A study was conducted to examine the prevalence of dental fluorosis between adolescents from 1986-1987 and 1999-2004. The study found that adolescents who were between 12-15 years of age between 1999-2004 had a higher prevalence rate of 41% than adolescents between the same age group in the 1986-1987 survey (6).

  • Enamel Hypoplasia

Enamel hypoplasia is a defect in the enamel that develops during the formation of enamel which results in the development of thin enamel (7 ).” This is a condition that develops during your childhood when the teeth are forming and can lead to the development of white blotches on teeth. These stains can be removed by putting dental crowns on the affected teeth (8).

  • Presence Of Bacteria And Other Microbes

Did you know that your mouth is the ideal breeding ground for bacteria? Researchers reviewed the existing literature on white spots and found that the presence of bacteria in our mouth can contribute to the development of white spots (9). An overgrowth of bacteria can lead to the formation of bacterial plaques in your mouth, making it even more important to practice good oral hygiene.

You may not know this, but the food that you eat has an impact on what your teeth looks like. Food that is highly acidic and sugary can lead to the formation of white bumps on your teeth. How does that happen? When you have a high level of acid and sugar present in your mouth, it can lead to the mineral in your teeth wearing away, which results in the development of white spots (9).

You just read about the different factors that cause white bumps on teeth. Now, let us find out how we can get rid of these spots if you already have them and a few simple tips to prevent them from developing in the first place.

  • Resin Infiltration – A cost-effective procedure used by dentists today to treat white spots. In this procedure, the tooth is coated with hydrochloric acid, dried with an ethanol solution, and coated with a resin infiltrant. A study was conducted on children between the ages of 8 to 14 years to check the effect of the resin infiltration technique on white spots. After a six-month follow-up, the results showed that there was a significant reduction of white spot lesions in the children (10).
  • Microabrasion – A procedure highly recommended by orthodontists for removing white stains on teeth. In this procedure, acidic and abrasive materials such as hydrochloric acid and silicon carbide are used to remove the white stains from your teeth (11).
  • Dental Bleaching – With the advent of technology, doctors are coming up with various ways to keep you happy and smiling! One of the methods commonly used by dentists to get rid of white patches on teeth is dental bleaching. During this procedure, your dentist applies acid on your teeth, followed by an oxidizing agent on your enamel. Then it is put under a laser to speed up the lightening process (12). Going through two or three sittings of dental bleaching can help you get rid of those white patches on teeth and keep them pearlies shining.

These were the three ways to get rid of white spots permanently. If you do not have those white spots yet, then let us look into a few tips to prevent them.

5 Prevention Tips For White Spots On Teeth

You can follow these simple tips on how to prevent white stains on teeth:

  • Reduce Consumption Of Highly Acidic And Sugary Food – Making simple yet doable changes to your lifestyle can prevent you from developing white spots. High content of acid causes the minerals in our enamel to wear, resulting in many people being at risk of developing tooth decay. While there is nothing wrong with eating all these foods once in a while, too much consumption of these foods can lead to the white stuff on teeth we do not like. It is highly recommended that you wash your teeth with water after consuming these items to avoid developing white stains.
  • Use Fluoride Products – It seems ironic that excess fluoride can cause white bumps and now fluoride products can help get rid of them right? Researchers conducted a study on a group of 723 participants to see the effect of fluoride products on their teeth. They concluded that using a sodium fluoride mouth rinse every day reduced the amount of decay in the enamel (13). Dentists encourage using fluoride toothpaste recommended by the American Dental Association to maintain daily oral hygiene (14).
  • Use Dietary Fluoride Supplements – Excess fluoride can cause you to develop white dots on teeth. This is because fluoride helps in reducing the process of demineralization of your enamel and helps in the remineralization of enamel (3). The American Dental Association recommends a set of dietary fluoride supplements that can be given to children between the age of 6 to 16 years to prevent or get rid of the white spots (6).
  • Dental Veneers – These are thin coverings that protect your teeth from developing white spots and tooth decay. Going to your dentist and getting dental veneers fitted can help keep your teeth strong and healthy (15).
  • Good Oral Hygiene – Today, it is essential for adults and especially children to be educated on practicing good oral hygiene. Brushing your teeth twice a day, drinking water after consuming sugary food, and flossing can go a long way in reducing the risk of developing white spots.

Using fluoride products, trying dental veneers, and practicing good oral hygiene can help you in preventing these white stains. You probably did not know this, but there are various types of stains that can develop on your teeth. Let us delve in further to understand more about them.

Types Of Stains On Teeth

Dentists recognize two types of stains that can develop on your teeth. They are:

  • Intrinsic Stains – As the name suggests, this is a type of stain that is found on the inner layer of your teeth. This stain develops on the hard layer that lies beneath the enamel called dentin, creating those annoying stains. Intrinsic stains are caused by various factors such as fluorosis, age, or oral trauma (16).
  • Extrinsic Stains – These are stains that are found on the enamel of our teeth and are caused by several factors such as consumption of acidic food, dark-colored food, or smoking (16).

Be it intrinsic stains or extrinsic stains, both of them are bad for our teeth and can make us think twice before we smile. Let us read further to find out what kind of vitamin deficiency causes white spots to develop.

What Vitamin Deficiency Causes White Spots on Teeth?

There are some important nutrients that are essential for the development of healthy teeth. Lack or absence of these nutrients can cause white spots to develop. These are the following nutrients that are known for white patches on teeth. They are:

  • Vitamin D – Have you heard your doctors say get some sun on you every day? The sun is a good source of vitamin D along with foods such as fish. This is a vitamin that is essential for healthy teeth and bones. Studies have shown that low vitamin D levels can negatively impact tooth mineralization (17). This can lead to you developing white spots on your teeth.
  • Calcium – Calcium is a nutrient that we all know is required for the development of strong teeth and bones. The deficiency of calcium can lead to tooth decay, weak teeth, and the development of osteoporosis (18). Dentists recommend eating foods rich in calcium such as milk, cheese, and yogurt. For those of you who are lactose intolerant, the American Dental Association recommends non-dairy options such as tofu, beans, and almonds (19).

Summary

White spots on teeth are those irksome white stains that develop on your teeth due to several factors, ranging from overconsumption of fluoride and accumulation of bacteria in your mouth to high consumption of acidic food. And if you’re thinking “how to get rid of white spots on my teeth?” The answer is simple. Following a few easy tips such as maintaining good oral hygiene, drinking lots of water, and avoiding highly acidic and sugary food can help in reducing the risk of developing white spots. If these tips fail, getting dental veneers or bleaching done from your dentist can give you healthy and shiny teeth!
