6. What happens if you don't take good care of your teeth? • cavities • gum disease • tooth loss

7. Cavities What is a cavity? A cavity is a small hole in a tooth, also known as tooth decay. When your teeth decay, they lose their strength. The decay can spread throughout your tooth.

8. Cavities What causes cavities? One thing that plays a big part in causing cavities is plaque. Plaque is a sticky, clear film that forms on your teeth 24 hours a day. Bacteria in plaque make acid that attacks tooth enamel -- the hard outer layer of each tooth. The stickiness of plaque keeps the harmful acids against the teeth. The acid breaks down tooth enamel and forms a cavity. Repeated acid attacks make cavities grow bigger.

9. Cavities Cavities do not go away by themselves. Only a dentist can fix a cavity, by removing the decay and filling the hole.

10. Gum Disease Gingivitis If plaque is not removed with daily brushing and cleaning between teeth with floss, it hardens into tartar. Tartar must be removed, because it makes your teeth harder to clean. If tartar is not removed, it can lead to gingivitis, an early form of gum disease. Gingivitis means inflamed gums.

11. Gum Disease • Signs of gingivitis: • Gums that bleed easily • Bright red gums • Gums are tender to touch • Mouth sores • Swollen gums • Gums look shiny

12. Gum Disease Periodontitis If not treated, gingivitis can lead to periodontitis. Periodontitis is when infection spreads from the gums to the tissues and bones that support the teeth. In time, teeth become loose and fall out.

13. Gum Disease • Signs of periodontitis: • Gums that bleed easily • Bright red gums • Gums are tender to touch • Swollen gums • Bad breath • Loose permanent teeth

22. Take Good Care of Teeth • There are three main ways to keep teeth “pearly white” and healthy: • 1. Brush and floss • 2. Good eating habits • 3. Regular dental visits.

23. Take Good Care of Teeth Proper Brushing Brushing cleans food and plaque off teeth and fights the acid that causes cavities. Brushing also makes your mouth feel clean, and your breath smell good. Brush twice a day with fluoride toothpaste. Fluoride toothpaste helps prevent cavities by protecting tooth enamel.

24. How To Brush Place your toothbrush at a slight angle to the gums. Move the brush back and forth gently in short strokes.

25. How To Brush 1 Brush the top, front, and back sides of each tooth.

26. How To Brush 1 2 To clean the inside surface of front teeth, tilt the brush like this. Make several up-and-down strokes.

27. How To Brush 1 3 2 Brush your tongue to remove bacteria and keep your breath fresh.

28. How To Brush A toothbrush does not last forever. If your toothbrush looks like this with bent or broken bristles, it’s time to toss it and get a new one. Use a toothbrush that is easy to hold and easily reaches all tooth surfaces.

29. How To Floss You should floss once a day. Flossing removes bits of food and plaque from between teeth, where a toothbrush can’t reach. Floss gently. It doesn’t take a lot of muscle to remove the plaque and debris from between your teeth.

30. How To Floss Break off about 18 inches of floss. Wind most of it around one of your middle fingers. Wind the rest around the same finger of the other hand.

31. How To Floss 1 Hold the floss tightly between the thumbs and forefingers. Gently insert it between the teeth.

32. How To Floss 1 2 Curve the floss into a “C” shape against the side of the tooth.

33. How To Floss 1 3 2 Rub the floss gently up and down, keeping it pressed against the tooth. Don’t jerk or snap the floss.

34. How To Floss 1 3 2 4 Floss all your teeth. Don’t forget to floss behind your back teeth.

35. Good Eating Habits What you eat and drink, and how often, affects the amount of acid in your mouth. Plaque bacteria turn sugar and starches from food and drinks into acid. Every time you have sugary snacks and drinks, acid attacks your teeth.

36. Good Eating Habits If you have sweets, eat or drink them with meals, because saliva helps wash acid off your teeth. If you need a snack between meals, choose things like fruit, low-fat cheese, low-fat yogurt, or raw vegetables.

37. Good Eating Habits It's OK to chew gum for about 20 minutes right after you eat as long as the gum is sugarless. Chewing sugar-free gum helps your mouth make more saliva to rinse acid off your teeth.

38. Visit the Dentist It is important to see a dentist regularly to be sure your mouth is healthy and to get your teeth cleaned. Even when you brush well, some plaque stays on your teeth. Over time, plaque hardens into tartar. Only a professional cleaning can remove tartar. If tartar is not removed, it can lead to gum disease.
