Yes. Cleaning your teeth between dental visits is required.
Thanks to better at-home care and in-surgery dental treatments, more people than ever before are keeping their teeth throughout their lives. Although some diseases and conditions can make dental disease and tooth loss more likely, most of us have a good deal of control over whether we keep our teeth into old age. A good homecare routine should contain 3 major components:
- Effective brushing
-
Cleaning in between the teeth
- Therapeutic products that either treat the caries infection, remineralize teeth, or maintain long-term oral health
-
Brush at least twice a day Many oral health professionals recommend brushing just before going to bed. When you sleep, saliva decreases, leaving the teeth more vulnerable to bacterial acids. Teeth should also be brushed in the morning, either before or after breakfast, depending on your schedule.
-
Brush no more than three times a day Brushing after lunch will give you a good mid-day cleaning. Remember, though, that brushing too often can cause damage over time.
-
Brush lightly Brushing too hard can cause damage. Once plaque has hardened into calculus (tartar), brushing can't remove it, so brushing harder won't help. Try holding your toothbrush the same way you hold a pen. This encourages a lighter stroke.
-
Brush for at least two minutes. Set a timer if you have to, but don't skimp on brushing time. Longer is fine, but two minutes is the minimum time needed to adequately clean all your teeth. Many people brush for the length of a song on the radio. That acts as a good reminder to brush each tooth thoroughly.
-
Have a standard routine for brushing. Try to brush your teeth in the same order every day. Some oral health professionals feel that this helps patients remember to brush all areas of their mouths. If you do this routinely, it eventually will become second nature. For example, brush the outer sides of your teeth from left to right across the top then move to the inside and brush rights to left. Repeat the pattern for your lower teeth.
-
Always use a toothbrush with "soft" or "extra soft" bristles. The harder the brush, the greater the risk of harming gum tissue.
-
Change your toothbrush regularly. As soon as the bristles begin to splay, the toothbrush loses its ability to clean properly. Throw away your old toothbrush after three months or when the bristles flare, whichever comes first. If you find your bristles flaring much sooner than three months, you may be brushing too hard. Try easing up.
- Oral health-care professionals say, "It's not the brush, it's the brusher," meaning that the exact type of brush you use isn't nearly as important as your brushing technique and diligence. Any brush will be a good tool, but you have to know how to use it.
- Electric is fine, but not always necessary. Electric or power-assisted toothbrushes are a great alternative to manual brushes. They are especially useful for people who are less than diligent about proper brushing technique or for people with physical limitations that make brushing difficult. As with manual brushes, choose soft bristles, brush for at least two minutes and don't press too hard or you'll damage your gums.
- Choose the right toothpaste for you. It can be overwhelming to face the huge number of toothpaste choices in the average supermarket. Remember, the most common name can just mean the company with the biggest marketing budget, not the best product.
How to Brush
Bass Brushing Technique
-
Hold the head of the toothbrush horizontally against your teeth with the bristles part way on the gums.
-
Tilt the brush head to about a 45-degree angle, so the bristles are pointing under the gum line.
-
Move the toothbrush in very short horizontal strokes so the tips of the bristles stay in one place, but the head of the brush waggles back and forth. Or use tiny circular motions. This allows the bristles to slide gently under the gum.
-
Do this for about 20 strokes. This assures that adequate time will be spent cleaning away as much plaque as possible. Note: this is a very gentle motion. In healthy gums, this should cause no pain. Brushing too vigorously or with large strokes can damage gum tissue.
-
Repeat for every tooth, so that all tooth surfaces and gum lines are cleaned.
-
For the insides of your front teeth, where the horizontal brush position is cumbersome, hold the brush vertically instead. Again, use gentle back and forth brushing action.
-
To clean the biting or chewing surfaces of the teeth, hold the brush so the bristles are straight down on the flat surface of the molars.
-
Gently move the brush back and forth or in tiny circles to clean the entire surface. Move to a new tooth or area until all teeth are cleaned.
-
You can clear even more bacteria out of your mouth by brushing your tongue. With your toothbrush, brush firmly but gently from back to front.
-
Floss once a day. Although there is no research to recommend an optimum number of times to floss, most dentists recommend a thorough flossing at least once a day. If you tend to get food trapped between teeth, flossing more often can help remove it.
-
Take your time. Flossing requires a certain amount of dexterity and thought. Don't rush.
-
Choose your own time. Although most people find that just before bed is an ideal time, many oral health professionals recommend flossing any time that is most convenient to ensure that you will continue to floss regularly. Choose a time during the day when you can floss without haste.
-
Don't skimp on the floss. Use as much as you need to clean both sides of every tooth with a fresh section of floss. In fact, you may need to floss one tooth several times (using fresh sections of floss) to remove all the food debris. Although there has been no research, some professionals think reusing sections of floss may redistribute bacteria pulled off one tooth onto another tooth.
-
Choose the type that works best for you. There are many different types of floss: waxed and unwaxed, flavoured and unflavoured, ribbon and thread. Try different varieties before settling on one. People with teeth that are closely spaced will find that waxed floss slides more easily into the tight space. There are tougher shred-resistant varieties that work well for people with rough edges that tend to catch and rip floss.
How to Floss
How you hold the floss is a matter of personal preference. The most common method is to wind the floss around the middle fingers, then pull it taut and guide it with your index fingers. You also can wind it around your index fingers and guide it with your thumb and middle fingers, or simply hold the ends of the floss or use a floss-guiding tool. (If you have a fixed bridge, a bridge threader can help guide floss under the bridge for better cleaning.) How you hold the thread is not as important as what you do with it. If you can't settle in on a good method, ask your dentist or hygienist for suggestions.
-
Hold the floss so that a short segment is ready to work with.
-
With light to firm pressure to skim off plaque in that area. Do not press so hard that you injure the gum.
-
Repeat for all sides of the tooth Guide the floss gently between two teeth. If the fit is tight, use a back-and-forth motion to work the floss through the narrow spot. Do not snap the floss in or you could cut your gums.
-
Hold the floss around the front and back of one tooth, making it into a "C" shape. This will wrap the floss around the side edge of that tooth.
-
Gently move the floss toward the base of the tooth and up into the space between the tooth and gum.
-
Move the floss up and down, including the outermost side of the last tooth. Advance the floss to a clean segment for each tooth edge.
Other Ways to Clean Between the Teeth
Many people have larger spaces between their teeth and need additional tools, called interdental cleaners, to remove food particles and bacterial plaque adequately. You may have larger spaces that need extra care if you have had gum surgery or if you have teeth that are missing or out of alignment. Small interdental brushes are tiny bristle or filament brushes that can fit between teeth and come in a variety of sizes and handle designs. These brushes clean better than floss when the gum tissue does not completely fill the space between your teeth. These little brushes also can help people with orthodontic bands on their teeth to remove bacterial plaque from around the wires and brackets. Another tool for cleaning between teeth is wooden interdental cleaners. These long, triangular strips of wood can be softened and used to clean between teeth. You can find these interdental cleaners at most chemists and supermarkets. Your dentist or dental hygienist can show you how to use these cleaners to remove plaque between your teeth.
