The most common dental diseases are tooth decay and gum disease. This is true for both children and adults, but these diseases are also among the most easily treated. Tooth decay begins with the erosion of tooth enamel, which eventually leads to cavities—holes in your teeth. Untreated cavities will worsen over time until the entire tooth is undermined. Untreated cavities can also lead to infections, which can reach your root canals, gums, and even jawbone. Tooth decay and gum disease can eventually lead to tooth and even bone loss. But, as mentioned, prevention is rather simple.
The key to avoiding these issues is prevention — and with the right daily routine, you can keep your smile healthy and strong for life. Here are eight proven preventive dentistry tips to protect your teeth and gums.
1. Brush Twice a Day, Every Day
This simple habit remains one of the most effective ways to prevent dental disease. Brush your teeth twice a day for at least two minutes using a soft-bristled toothbrush and fluoride toothpaste. Morning brushing removes overnight bacteria, and brushing before bed eliminates food particles and plaque that accumulate throughout the day.
Pro Tip: Replace your toothbrush every three to four months, or sooner if the bristles are frayed.
2. Use Fluoride Toothpaste
Fluoride strengthens tooth enamel, making it more resistant to acid attacks from plaque and bacteria. Consistent fluoride use is one of the most effective ways to reduce the risk of cavities and protect your teeth long-term.
Pro Tip: If you’re prone to cavities or have sensitive teeth, talk to your dentist about prescription-strength fluoride toothpaste.
3. Clean Your Tongue Too
Your tongue can harbor bacteria that contribute to decay, gum disease, and bad breath. Gently brush your tongue every time you brush your teeth, or use a tongue scraper for a more thorough clean.
Pro Tip: If you notice a coating or buildup on your tongue, it’s a sign you’re leaving bacteria behind — daily cleaning will help keep your mouth fresher and healthier.
4. Floss Every Day
Brushing alone can’t reach the spaces between your teeth or below the gum line where plaque often hides. Floss at least once a day to remove food debris and bacteria in these hard-to-reach areas and lower your risk of gum disease and cavities.
Pro Tip: If traditional floss is difficult to use, try floss picks, interdental brushes, or a water flosser for the same benefit.
5. Limit Sugar and Acidic Foods
Sugar feeds the bacteria that produce enamel-eroding acids. Starchy snacks and sugary drinks are especially harmful because they stick to your teeth and create a breeding ground for decay. Acidic foods and beverages — like soda, citrus, and wine — can also weaken enamel over time.
Pro Tip: Rinse with water after consuming sugary or acidic foods, and avoid sipping sugary drinks throughout the day.
6. Use an Antibacterial Mouthwash
Adding an antibacterial or fluoride mouthwash to your routine helps reduce plaque, control bacteria, and strengthen enamel. Rinse once or twice daily, ideally after brushing and flossing, for maximum benefit.
Pro Tip: Choose an alcohol-free mouthwash to avoid dryness, which can increase your risk of decay and gum issues.
7. Pay Attention to Warning Signs
Your daily hygiene routine is also an opportunity to monitor your oral health. If you notice bleeding gums, persistent bad breath, sensitivity, or any unusual changes in your mouth, contact your dentist right away. Early intervention can prevent minor issues from becoming serious problems.
Pro Tip: Never ignore signs of inflammation or discomfort, they often indicate underlying issues like early gum disease or infection.
8. Visit Your Dentist Twice a Year
Even the best at-home care can’t replace professional cleanings and exams. Visiting your dentist every six months allows them to remove hardened tartar, spot early signs of decay or gum disease, and recommend personalized preventive care.
Pro Tip: If you’re prone to gum disease, cavities, or other oral health concerns, your dentist may recommend more frequent visits.
