While the reasons for cavity formation can vary from person to person, there are several key principles about cavity development that I share with my patients to help address their concerns:
- How do cavities form?
- How can you promote re-mineralization of your teeth?
- When is the best time to brush your teeth?
How Do Cavities Form?
Our teeth are composed of minerals, and every time we consume sugary or starchy foods, the bacteria in the plaque on our teeth begin producing acid. This acid then erodes the enamel, which serves as the protective layer for our teeth. When the pH in your mouth drops below a critical level and becomes more acidic, your teeth start losing their essential minerals.
Typically, it takes about 30-60 minutes after eating or drinking for the pH in your mouth to return to its normal state. However, if you do not allow your mouth enough time to recover and consume something else high in sugars or starch right after, the acid production resumes, and the cycle continues.
For example, drinking a can of soda in 10 minutes is much better than sipping it over an hour. The shorter exposure time to the acidic beverage means your mouth faces less prolonged acid attack, allowing your teeth to start the re-mineralization process sooner.
How Can You Help Your Teeth Re-mineralize?
Saliva is your ally! Saliva plays a crucial role in protecting your teeth. It acts as a natural buffer against harmful substances and helps wash them away. The minerals found in saliva, such as calcium and phosphate, are also present in our teeth, aiding in the re-mineralization process after meals.
However, sometimes saliva alone isn’t enough. This is where fluoride comes into play. Using fluoride toothpaste or drinking fluoridated tap water allows these beneficial properties to integrate into your saliva, offering additional protection for your teeth. Consequently, when your teeth are recovering from the acids produced by sugary juices or snacks, they can utilize the fluoride minerals in your saliva to strengthen and reinforce the enamel, making it more resistant to decay.
When is the Best Time to Brush Your Teeth?
Everyone knows that brushing twice a day is essential, but timing is also crucial. Plaque-causing bacteria multiply in your mouth while you sleep, making it beneficial to brush your teeth first thing in the morning. This practice not only removes plaque and bacteria but also introduces fluoride into your mouth before your first meal of the day, helping to minimize acid-forming particles from breakfast.
If you prefer to brush after meals, ensure you wait at least 30 minutes. Brushing immediately after eating can potentially remove the helpful minerals from your saliva. If you need to rinse after a meal, consider drinking water or chewing sugar-free gum to stimulate saliva flow, which can help keep your teeth healthy.
Finally, brushing before bed is crucial to limit prolonged acid exposure during the night. In general, brushing twice daily is essential for removing harmful bacteria and particles from your mouth. You can enhance your oral hygiene routine by brushing immediately after waking and right before sleeping.
Conclusion
If you’re still experiencing cavities despite brushing your teeth twice a day, it’s crucial to examine your dietary habits, brushing techniques, and timing. By understanding how cavities form and how to promote the re-mineralization of your teeth, you can take proactive steps to protect your oral health.
