Ever wondered what keeps your teeth protective? Its tooth enamel teeth, the hardest part in the human body. It keeps your smile bright, healthy, and radiant while protecting the sensitive parts underneath from the grind of eating, chewing and drinking.
However, once your enamel is eroded or impacted, your teeth become vulnerable to damage and sensitivity. Poor dietary habits and a lack of proper oral hygiene can damage even the toughest armour, leading to teeth yellowing, tooth decay, and other underlying problems.
The good news is that you can naturally protect and strengthen your tooth enamel. All you need to do is protect your teeth from the acids found in food, sugar, germs, and bacteria. With proper dental care and regular visits to the Hope Island dentist, you can restore a healthy, confident and radiant smile.
Let’s get started!
What is Tooth Enamel?
Enamel is the toughest outer layer of your tooth, made up of minerals such as hydroxyapatite, calcium, and phosphate. This is a protective shield that acts as a barrier between the softer, nerve filled inner part of your tooth and the harsh layer. Other minerals in tooth enamel are:
- Fluoride
- Carbonate
- Magnesium
- Sodium
Tip: Dentists often recommend teeth remineralisation as one of the best ways to strengthen tooth enamel while restoring your beautiful smile.
What are the Common Causes of Weaken Tooth Enamel?
It is important to know the enemy when protecting the robustness of your tooth enamel. Enamel erosion is often caused by two main factors:
Acid Attack:
Eating sugary and starchy foods harbours bacteria in your mouth that can product lactic acid, causing enamel damage. Beverages like tea, coffee and soft drinks also contain acid and caffeine that can weaken your enamel over time. Other health conditions, like acid reflux or GORD, can also produce acid, leading to enamel deterioration.
Physical Wear and Tear:
Believe it or not! Bruxism or teeth grinding, can wear down your mineralised enamel over time. This can even cause tiny fractures and other issues. In fact, using a hard bristled toothbrush on a daily basis can cause wear and tear near the gum line.
Daily Habits to Strengthen Your Tooth Enamel
Below are some easy ways to strengthen tooth enamel without any painful or expensive treatment. Good dental hygiene starts within a home:
1. Regular Yet Gentle Brushing
Start with the basics! Use a soft bristled toothbrush or an electric one to prevent abrasive scrubbing to remove stuck food particles. Professional dentists in Hope Island recommend brushing gently in small and circular motions. It is a good brush at a 45 degree angle when brushing the gumline.
For good dental hygiene, you should brush twice a day for at least 2 minutes and clean your tongue to help combat lingering bacteria. This habit can protect and strengthen your tooth enamel.
2. Use Fluoride Toothpaste
There is no denying that fluoride is one of the best toothpastes to restore tooth enamel. Fluoride reacts with the minerals in your enamel, making the shield stronger and more resistant to acid attacks and sugary foods.
3. Drink Enough Water to Prevent Mouth Dryness
Cultivating this daily habit not only keeps you hydrated but also prevents enamel damage. Drinking enough water naturally strengthens your teeth by flushing away stuck food particles. This keeps acid and bacteria at bay while promoting saliva flow. Drink plain water instead of carbonated drinks or other beverages.
4. Daily Flossing Can Do Wonders
There is a misconception that flossing is for protecting gums. Of course, it removes the plaque, bacteria and acid build up from your mouth, but also prevents enamel erosion from nooks and crannies. You should floss twice a day for the best results.
What are the Dietary Guidelines to Support Healthy Enamel?
What you eat plays a pivotal role in maintaining healthy and strong enamel. Here are a few things to remember:
1. Add Daily Products for Calcium
Enamel needs calcium to strengthen. It is good to consume milk, cheese and yogurt for calcium intake. Cheese can stimulate saliva production and help prevent acid buildup in your mouth.
2. Leafy Greens, Healthy Teeth
Spinach, broccoli and kale are packed with calcium and fibre. These provide a natural scrub for your teeth, helping protect the enamel layer.
3. Dry fruits
You should eat soaked almonds daily in the morning as they contain calcium and healthy fats. These can provide your teeth with enough nutrition while keeping acid producing bacteria at bay.
4. Include Vitamin D in your Diet
Calcium works when you consume vitamin D rich foods. Good sources include salmon, fortified foods, and Australian sunshine.
5. Vitamin K2 is Essential
It is one of the key vitamins that help keep your bones and teeth strong and healthy. You can find it in organ meats and grass fed dairy.
6. Eat Crunchy Food
Instead of eating sugary and starchy foods, eat apples, celery, and carrots. These work as a detergent food that stimulates saliva and scrubs away food debris.
How to Remineralise Affected Tooth Enamel?
It is good to visit your Hope Island dentist if you want to remineralise your tooth enamel. They usually apply high concentration fluoride gel or varnish to your teeth to provide a sturdy layer. This will speed up the remineralisation process and strengthen the weaken spots. This is a painless, quick treatment often performed during your regular dental checkup.
However, in a case of poor condition due to cavities and decay, they can apply sealants and bonding to the enamel, wrap special films around the teeth (also known as pronamel), or replace a broken tooth with a dental implant.
Wrapping Up
Your tooth enamel is a valuable part of your body, protecting against acid attacks, physical wear and tear, and bacterial buildup. Strengthening it naturally through gentle brushing, proper food habits, and oral hygiene can make a world of difference. Take care of your bright and shiny whites by keeping your enamel protected!
