The advice from dental experts for keeping your teeth clean sounds simple enough: Brush twice a day and floss. But choosing among the many products available to help you do this can be daunting. Electric toothbrush or manual? Soft or hard bristles? String floss or water flosser?
The right answers depend partly on your preferences. Hopefully what you experience with any toothbrush is that youre getting your teeth clean, and then youre going to want to use it again, says Edmond R. Hewlett, a professor at the UCLA School of Dentistry in Los Angeles and a consumer adviser for the American Dental Association (ADA).
But there are tooth-care products with clear advantages. We explain which dental hygiene strategies work best and what to consider when picking products.

Q: Are electric toothbrushes better for your teeth?
A: Most evidence suggests that they are, at least a little. A analysis of previously published studies by Cochrane, an independent, London-based panel of experts, found that over several months, powered brushes removed 21 percent more plaque and reduced gum inflammation by 11 percent more than manual brushes. Two more recent studies, by scientists who had funding from companies that make toothbrushes, found similar results.
But the real-life significance of that research might not mean much for your overall oral health. Electric brushes might be better for some people, says Olivia Sheridan, a professor of clinical restorative dentistry at the University of Pennsylvania, because they can be easier to use for those who lack manual dexterity or have braces or permanent retainers, or those who care for someone who needs help brushing their teeth. But your technique may matter more than whether you use a manual or electric brush. Both types of brushes can be completely effective in plaque removal and in helping to prevent gum disease, says Sheridan.

What features should you look for? Cleaning ability is key, and its the most significant factor in Consumer Reports electric toothbrush scores. You should also seek out brushes with features such as a two-minute timer and a pressure sensor. The ADA says that most people brush their teeth for less than a minute, so a built-in timer can help. A pressure sensor can warn you if youre pressing too hard with your brush, which can damage gums and enamel. Sheridan also recommends looking for brushes that pause when its time to move from one section of your mouth to the next.
Q: What kind of bristles are ideal?
A: Although youll find manual toothbrushes with bristles ranging from extra-soft to hard, medium- or hard-bristle brushes are best reserved for tasks such as cleaning the grout in your kitchen or bathroom tile. For your teeth, dental experts say you should use a soft- or extra-soft-bristle brush.

Thats because harder bristles can injure your delicate gum tissue. They can also potentially damage your teeth, says Clifton Carey, a professor at the University of Colorado School of Dental Medicine at Anschutz Medical Campus.
Q: Which is better, a rotating or a sonic electric toothbrush?
A: Both kinds can do a great job of cleaning your teeth. Rotating toothbrushes have a round head that rotates or oscillates. Sonic brushes have a more typical elongated head shape resembling a manual brush, with bristles that move side to side so quickly they produce an audible hum.
Some research suggests that rotating toothbrushes may have a slight edge over sonic types. But a analysis in the Journal of the American Dental Association designed to assess real-world effectiveness concluded there wasnt enough evidence to pick a winner. And testing by Consumer Reports concurs: We found models of both types that performed well.

If youre not sure which type of electric brush youll like, check to make sure that you can return it if you decide its not right for you.
Q: Do you really need to floss?
A: Yes. You may have rejoiced over headlines a few years back that claimed theres not much evidence supporting flossing. And in , even the Cochrane panel characterized the evidence showing that flossing helps reduce gum disease as low certainty, with inconsistent results.
But dont toss out your dental floss yet. Although the evidence might not be especially rigorous, regular flossing is supported by basic biology, experts say. When done correctly, flossing removes bacteria in parts of your mouth that brushing cant get to. Good flossing technique generally involves gently rubbing the floss strand in a C-shape against both sides of each tooth and at the gumline.

Q: Which toothpaste should you use?
A: Any toothpaste that has fluoride should do the trick. Thats the most important ingredient because it prevents cavities and helps you avoid tooth decay by strengthening the enamel. Fluoride is so important that the ADA doesnt provide its Seal of Acceptance to fluoride-free toothpastes.
There are other ingredients in some toothpastes that you may want to stay away from. For example, research has found that people who frequently get canker sores may get fewer ones when they avoid toothpastes that contain sodium lauryl sulfate.
Various toothpaste ingredients fall in and out of fashion. We have to be very careful of those fads, says Dawn Smith, chair of the Department of Dental Hygiene at Howard Universitys College of Dentistry in D.C. Thats because it can take a while for researchers to discern whether a particular ingredient is safe and effective.

One newer trend has little evidence to support it: activated charcoal toothpastes, which are often marketed as whiteners. But some could cause damage, according to a paper in the British Dental Journal. Charcoal can be abrasive, which can wear down your enamel, damage your gums, and lead to tooth sensitivity. And many charcoal toothpastes dont contain fluoride.

Q: Should you use mouthwash?
A: Its fine to use mouthwash, says Smith, but its not strictly necessary and cant take the place of brushing and flossing.
Certain types of mouthwash can help with specific conditions. For example, prescription rinses with chlorhexidine, an antimicrobial, can help people who have periodontal disease or are at high risk for tooth decay, Hewlett says.
And if you live in an area where your water isnt fluoridated (or you dont drink tap water), you may want to consider adding a fluoridated mouth rinse to your familys daily dental care routine, Smith suggests. Thats especially true if you have kids, and its something that can be helpful even if theres fluoride in your toothpaste.

Q: Are teeth whiteners worth trying?
A: Some of the stains on the outside of your teeth can be removed during a typical dental cleaning. But you might wonder about bleaching your teeth, either at your dentists office or by using an at-home kit.
The active ingredient in most tooth bleaching products isnt the household bleach you use for laundry but hydrogen peroxide (or a related compound).
At-home bleaching, which can involve products such as bleaching strips or gels and trays, can be effective, says Kenneth Markowitz, an associate professor at the Rutgers School of Dental Medicine in Newark. But it generally takes longer to see results with those treatments than with professional whitening, because in-office treatments are done with higher concentrations of peroxide.
Still, its best to avoid trying to whiten your teeth quickly, he says. Thats because the higher the concentration of bleaching agents used, the more likely you are to experience the main side effects of whitening: gum irritation and tooth sensitivity (which often involves a tingly feeling of pain). High concentrations could even damage teeth.

Instead, bleaching is best if done slowly over time, using low concentrations of bleaching agents. Carey recommends that people who bleach at home read the products directions and follow them exactly.
Q: How often do you need a teeth cleaning?
A: Youve probably heard you should get cleanings every six months. But a Cochrane review found that adults who timed their visits based on their risk factors (which you can discuss with your dentist) did no worse than people who followed the six-months rule.
The ADA says tailoring your visits to your individual health risks is a good one.
If youre not at high risk for cavities your teeth are otherwise healthy and you dont eat a lot of sweets, for example seeing a dentist once a year may be sufficient for you, Carey says.
On the other hand, people at higher risk may need to go in more often. If you struggle with a dry mouth, for instance, a common occurrence for people who are taking multiple medications, Carey says you may need to see your dentist more frequently, because saliva is one of the biggest protectors of teeth.

If you want to clean your teeth effectively, you need to start with the right toothbrush. This post focuses on manual and electric toothbrushes as theyre the most common types of toothbrushes. However, be sure to look at our blog post on types of toothbrushes to learn if your oral health could benefit by using another type of toothbrush in addition to what you currently use. After all, sometimes is necessary to use more than one type of brush.
Studies, including one from the NCBI,¹ have proven that people who use electric toothbrushes have healthier gums, fewer instances of tooth decay, and maintain the integrity of their teeth for longer than those who rely on manual toothbrushes. Because they also help inhibit aggressive brushing, electric toothbrushes are often advised for people with braces, gum disease, or other sensitivities.
Youre off to a great start by brushing with an electric toothbrush, but you want to make sure youre using the right technique. Refer to our blog post on how to brush your teeth to learn the correct angle, direction, and more for your daily brushing routine.
When choosing a toothbrush, we recommend one with a soft or extra-soft bristle head. Hard, or stiff, bristles can damage your tooth structure and be harsh on your gums. Theres a demand for hard bristles because many people mistakenly believe theyre more effective than soft ones. Its also easier and more profitable for manufacturers to produce them instead of educating consumers on why they shouldnt use them.
Many people think you need to apply a lot of pressure when brushing your teeth to achieve a proper cleaning. But too much can wear down your enamel and cause your gums to recede. Instead, apply gentle pressure by allowing the toothbrush to do most of the work. An electric toothbrush makes this easier to accomplish, so you might want to consider switching from a manual one if you havent already done so. Some electric brushes, such as Sonicare, even come with pressure sensors.
If you prefer using a manual toothbrush, you can achieve the proper grip by holding the brush with your fingertips instead of your entire hand. It might seem strange at first, but it will soon feel natural if you stick with it.
The American Dental Association (ADA) recommends brushing twice a day for two minutes each time with fluoride toothpaste.² To help prevent cavities, never go to sleep without brushing your teeth first. Brushing twice a day can also help whiten your teeth by removing food and drink residue that can lead to plaque and tarter. If youre interested in obtaining whiter teeth, check out another one of our blog posts that offers some great teeth whitening tips.
We suggest replacing your toothbrush every three to four months, but you can change it more often if you were recently sick and want to avoid reinfection. We also suggest replacing your brush sooner if you notice bristle wear.
Yes, the ADA has recommended using fluoride toothpaste since the s. Long-deemed safe and effective, fluoride strengthens the enamel and prevents tooth decay.
If you prefer a non-fluoride option, studies have determined that toothpastes containing hydroxyapatite can rebuild lost enamel. Hydroxyapatite is also an excellent choice for medical patients who have difficulty using fluoride, such as those with thyroid issues.
Because acidic foods and drinks like tomato sauce and orange juice can soften enamel, its best to avoid brushing your teeth for 30 minutes after intake while your enamel is weakened. Instead, swish water around your mouth to help neutralize the acids in the meantime.
Regular brushing is the key to healthy teeth and gums. However, excessive brushing more than three times a day can cause receding gums, teeth abrasions, and sensitive teeth.
If you use a toothpaste with fluoride or hydroxyapatite, its best to spit it out instead of rinsing it from your mouth with water after brushing. Rinsing washes it from your teeth and reduces its effectiveness. Its perfectly safe to leave trace amounts of fluoride or hydroxyapatite behind, especially since youre only using a pea-sized amount of toothpaste.
We believe you should always floss before you brush. We also believe you should rinse after you floss to help remove loose particles from your mouth before you brush your teeth.
Yes! The ADA recommends cleaning between your teeth once daily with dental floss or an interdental brush. Brushing without flossing is only about 60% effective in cleaning your teeth; thats because teeth consist of five surface layers and brushing alone addresses only three of those layers.
Flossing also helps prevent gum disease and helps maintain your overall health.
It takes only a few slight changes and developing some good habits to keep your teeth healthy for a lifetime and enjoy a confident, vibrant smile. Consider the above tips for your brushing regimen so that your teeth and your dentist will thank you for it!
