Dental Emergency

Are you having bleeding gums and teeth? Do not wait. This can be an alarming sign. 

Bleeding gums and teeth often signal an underlying issue that needs urgent attention. Whether you are experiencing minor bleeding with irritation or severe blood loss, it is better to diagnose it properly as soon as possible. 

There can be several reasons behind bleeding from gums and teeth. Let’s explore those.

Causes of Bleeding from Your Teeth and Gums

Poor Oral Hygiene

If you neglect daily oral care, you have a very high chance of bleeding from gums. 

  • Without proper oral care, plaque builds up around your mouth. If the plaque is not removed on time, it hardens into tartar, increasing the risk of gum inflammation.
  • Bacteria in the plaque release toxins that weaken the gum tissue making it more vulnerable to bleeding. 

Gingivitis and Periodontitis

If you are already suffering from gum disease, chances are you will have bleeding from your gums and teeth.

  • Gingivitis is the early stage of gum disease where your gums appear red and swollen. 
  • If you leave this untreated, it progresses into periodontitis. Periodontitis affects the bone supporting your teeth.
  • Your gums become tender in this condition. Hence, bleeding during regular brushing is common. 

Brushing and Flossing Too Hard

If you spot blood while brushing and flossing, run to an emergency dentist nearby. 

  • Applying too much pressure during brushing can wear down your gum tissue.
  • If you floss improperly, like snapping the floss against the gums, it can lead to small cuts and irritation.
  • Aggressive brushing for a prolonged time can cause gum recession, exposing the sensitive tooth roots.

Deficiencies of Vitamins

What you eat affects your oral health greatly.

  • If you lack Vitamin C, you will have weak gum tissue. A weak tissue is more prone to infections and bleeding.
  • Vitamin K deficiency impacts blood clotting, increasing the chances of prolonged bleeding of your gum.
  • Poor nutrition also slows down your body’s ability to heal and recover from any injury.

Hormonal Changes

If your hormone levels are fluctuating, it will have an impact on the gum.

  • Pregnancy, menstruation, and menopause increase the blood flow to your gums, causing tenderness and inflammation.
  • Hormonal shifts in your body can also affect how your body reacts to plaque, making it difficult for you to maintain gum health.

Tobacco Use

  • Tobacco weakens your body’s immune system, making it harder for your body to fight gum infections.
  • Studies show smokers are more prone to gum disease. Gum disease can often lead to bleeding and, eventually, tooth loss.
  • Tobacco also reduces the oxygen supply to your gums, slowing down the healing process. 

Medications

Sometimes, your medicines also contribute to gum bleeding as a side effect.

  • Aspirin and anticoagulants can make your gums bleed more easily.
  • Some medicines also lead to a dry mouth, reducing the saliva flow and increasing the risk of gum irritation.
  • If you are on some drugs that affect your immune system, your gums can become vulnerable to infections.

If you experience frequent bleeding from your gums and teeth, it is important you contact a dentist soon. Be aware of the underlying causes and take steps to steer clear of these. Ensure healthy teeth and a healthy life.
