Everything You Need To Know About Dental Plaque


Dental plaque is a sticky film that gets formed on your teeth due to the accumulation of bacteria. Keep in mind that the formation of plaque is common in people but it is important that you keep removing it so that the development of cavities, gum diseases and other oral problems can be prevented. The bacteria that form plaque also produce acids which can cause teeth decay. If plaque is not removed and left on the teeth for longer, it can harden and form tartar. Hence, it is very crucial that you understand the causes, the symptoms of plaque and the steps needed to take in order to keep your teeth away from plaque formation.

Symptoms of plaque

The symptoms are not always clear and they may or may not be detected. However, the common symptoms include:

  • Bad breath
  • Red and swollen gums
  • Fuzzy feeling on the teeth

Causes of dental plaque

When you eat food that contains excess carbohydrates and sugar such as soft drinks, cakes, pastry, candy, etc., they get stuck in your teeth and attract bacteria. These bacteria begin to feed on these food particles and produce acids that destroy the tooth enamel. Hence, if you do not brush your teeth and continue to eat such food items, the accumulation of bacteria, acids and leftover food particles can mix to form plaque.

Complications of dental plaque

If dental plaque is not treated on time, it may harden and form tartar which is very difficult to remove without the help of a dentist. Further, if tartar is left on teeth for an extended period, it can lead to the formation of cavities, infection in teeth, tooth loss, bad breath, gum diseases, etc.

Diagnosis of plaque

The diagnosis of plaque begins with an oral examination of the affected area, understanding your medical history, eating habits, etc. The dentist will use a small mirror to examine the severity of the condition.

Treatment of plaque

There have been various advancements and innovations in the field of dentistry but when it comes to plaque, the best step you can take to remove them is by maintaining good oral health. However, if your plaque doesn’t go away after following the above measures, you must visit a dentist who will use special techniques to remove plaque from your teeth. Your dentist may also recommend the use of dental sealants, fluoride treatment methods, etc. to address the issue.

Prevention of dental plaque

  • Brush your teeth twice a day using a soft toothbrush and toothpaste that contains fluoride.
  • Flossing is the best way to remove food particles stuck in between your teeth. When you floss, you don’t give bacteria a chance to grow.
  • Use a good mouthwash and rinse your mouth after every meal. If you use a good antibacterial mouthwash, it will kill the bacteria and prevent the formation of plaque.
