Why can mouth breathing be harmful to your teeth?

What is mouth breathing?

Mouth breathing is simply breathing through your mouth instead of your nose. While it may not seem harmful in the short term, chronic mouth breathing can seriously affect your oral health. Our nose is designed to filter, warm, and humidify the air we breathe in, functions that the mouth lacks. Therefore, constantly breathing through the mouth can lead to a dry and unhealthy environment in the mouth.

How Mouth Breathing Can Damage Your Teeth

The effects of mouth breathing go beyond just a dry mouth. Here are some key ways mouth breathing can harm your teeth and gums:

  1. Dry mouth and reduced saliva production
    Saliva plays a crucial role in protecting your teeth. It helps neutralize acids, wash away bacteria, and remove food particles. When you breathe through your mouth, your mouth dries out faster and saliva production decreases. This increases the risk of tooth decay because your teeth are exposed to harmful acids and bacteria for longer periods.

  2. Higher chance of cavities
    Without enough saliva to clean and protect the mouth, bacteria and food particles remain on your teeth longer. These bacteria convert sugars into acid, which can damage tooth enamel and cause cavities. People who frequently breathe through their mouth are therefore at an increased risk of tooth decay.

  3. Gingivitis (gum inflammation)
    A dry mouth can also lead to inflamed gums. Because saliva helps fight harmful bacteria, a lack of saliva can cause bacteria to build up along the gumline. This can lead to gingivitis, a condition that can develop into more serious gum diseases if left untreated.

  4. Bad breath (halitosis)
    Mouth breathing causes a dry mouth, which can contribute to bad breath. Saliva normally helps to wash away the bacteria that cause unpleasant odors. Without enough saliva, these bacteria continue to accumulate, resulting in an unpleasant smell.

  5. Teeth shifting and jaw problems
    Chronic mouth breathing can even affect the alignment of your teeth and jaw. In children, it can lead to abnormal jaw development and misaligned teeth, which may cause orthodontic problems. The position of the tongue plays an important role here; with mouth breathing, the tongue rests lower in the mouth, which can influence the growth of the upper jaw.

Why Mouth Breathing Is Bad for Your Oral Health

In addition to the direct damage to your teeth and gums, mouth breathing also has other negative effects on your overall oral health:

  • Increased risk of infectionsA dry mouth creates an environment where bacteria and fungi can grow more quickly, which can lead to oral infections such as thrush (a fungal infection).

  • Weakened defense mechanismsSaliva contains enzymes that help kill harmful bacteria. A lack of saliva allows these bacteria to thrive, increasing the risk of infections, tooth decay, and gum disease.

  • Less fresh breathWithout saliva to constantly cleanse your mouth, odor-causing bacteria remain inside. This results in worse breath, especially upon waking.

What can you do to prevent damage caused by mouth breathing?

If you notice that you regularly breathe through your mouth, especially at night, there are some steps you can take to protect your oral health and prevent damage to your teeth:

  1. Hydrate regularly
    Make sure to drink enough water to prevent dehydration. This can help keep your mouth hydrated and stimulate your saliva production.

  2. Use a humidifier
    A humidifier can increase the humidity in your bedroom, which can help prevent your mouth from drying out too quickly while you sleep.

  3. Using mouth tape
    If you notice that you often breathe through your mouth at night, you might try mouth tape can be an effective solution. By lightly taping your mouth shut while sleeping, you force yourself to breathe through your nose, which better protects your mouth and teeth.

  4. Regular visits to the dentist
    Visit the dentist regularly to keep an eye on your teeth and gums. Your dentist can detect early signs of damage caused by mouth breathing and advise you on preventive measures.

  5. Practice nasal breathing
    Try to consciously breathe through your nose during the day, so it becomes a habit at night as well. Nasal breathing is better for your teeth and your overall health.

Mouth breathing can cause more problems than you might initially think, especially when it comes to your dental health. It's important to take steps to protect the health of your mouth.
