How to Remove Tooth Decay Yourself

Tooth decay, or cavities, can cause pain, discolouration, and other dental issues if not treated right away. Fortunately, there are some steps you can take at home to help remove tooth decay and alleviate symptoms.

What Causes Tooth Decay

Dental cavities, commonly known as tooth decay, are one of the most common chronic diseases among adults worldwide. Tooth decay is caused by bacterial infections, which can damage the enamel on the tooth surface, leading to cavities.

Tooth decay occurs when food and drinks containing carbohydrates such as sugars and starches (e.g. soft drinks, cakes, sweets, biscuits and fruit juices) are left on the teeth for long periods of time.

Bacteria in the mouth combine with saliva to form a sticky film on the surface of the teeth known as plaque. Plaque then turns into acid, which attacks the teeth, causing tooth decay.

Other factors increasing the risk of tooth decay:

• Poor oral hygiene
• Lifestyle choices such as smoking and not brushing teeth regularly
• Certain medicines
• Dry mouth
• Certain medical conditions
• Excessive alcohol consumption

It is important to take preventive measures to help protect your teeth from tooth decay. These measures include regular visits to the dentist, brushing with fluoride toothpaste twice a day, using floss or interdental brushes, using mouthwash, and avoiding sugary or acidic drinks and foods.

If you think you may have tooth decay, it is important to speak with your dentist. Your dentist can diagnose the problem, provide appropriate treatment and advise on preventive measures to help keep your teeth healthy.

Practical Tips for Preventing Tooth Decay Yourself

Here are a few simple tips to help you remove tooth decay yourself:

1. Keep Your Teeth Clean – Brush your teeth twice a day and floss regularly to help keep food particles and bacteria from accumulating on your teeth. This includes brushing your tongue to remove bacteria and plaque.
2. Rinse with a Fluoride-based Mouthwash – Fluoride is a naturally occurring mineral that helps strengthen tooth enamel and reduce the risk of cavities. Rinse twice a day with a fluoride-based mouthwash to help remove plaque, bacteria, and food particles from between your teeth.
3. Use a Fluoride Toothpaste – Using fluoride-based toothpaste will help strengthen enamel and reduce the risk of tooth decay.
4. Regularly Visit the Dentist – Make sure to get regular checkups and professional cleanings at the dentist to help prevent cavities.
5. Look for Natural Remedies – There are several natural remedies to help reduce tooth decay, such as brushing with baking soda and massaging your gums with clove oil. Speak with your dentist before trying these remedies to make sure it’s a safe and effective way to remove tooth decay.
6. Avoid Sugary Foods and Drinks – Sugary foods and drinks are the primary sources of tooth decay, so avoiding them can help reduce your risk.
7. Reduce Your Stress – Stress can lead to increased acid production in the mouth, so try to practice stress-reducing techniques like mindfulness and exercise to reduce the risk of tooth decay.

Visiting your dentist: If you have tooth decay, the first and most important step is to visit a qualified dental professional. While it’s possible to address some of the symptoms at home to properly treat the decay and prevent it from spreading and causing further damage, a dental professional is needed for a proper examination and treatment.

Foods to Help Fight Tooth Decay

1. Eat generous amounts of fresh fruits and vegetables for their fibrous texture, which can help naturally clean plaque from teeth.
2. Limit your sugar intake and avoid acidic drinks like soda and juice. Sugar and acid can worsen tooth decay, so it's best to reduce their consumption.
3. Eat more foods that contain calcium and Vitamin D, such as dairy, salmon and broccoli.
4. Avoid starchy foods, such as white bread, chips and cookies, as they can stick to teeth and cause further problems with plaque and decay.
5. Consume whole grains and nuts, which contain minerals and help to promote healthy teeth.
6. Enjoy foods that are high in probiotics, such as yoghurt and fermented vegetables, which can help to ward off tooth decay.
7. Drink water throughout the day, especially after eating, to help flush out bacteria and food particles.
