NEED FOR SPEED 2015 CRACK MANUALIn fact, a gentle touch with a soft-bristled toothbrush-whether manual or electric-is the safest bet. And experts say that brushing too forcefully with any kind of toothbrush may increase the likelihood of gum recession and damaged tooth enamel. It found that manual and electric toothbrushes had similar effects on intact enamel, but that on worn enamel, manual toothbrushing abraded dentin more.īut there’s an important caveat: In this study, the manual brushing simulation used a lot more force than the powered brush simulation. They found that sonic toothbrushes caused the most abrasion to the dentin, followed by oscillating, and that manual toothbrushes-especially those with rippled bristles-created the least.Īnother simulated brushing study, this one published in 2013 in the journal Clinical Oral Investigations, had somewhat different results. Abrasions to the dentin increase tooth sensitivity and can hike cavity risks.įor the study, researchers took dentin samples from teeth and then used a machine that simulated the effects of eight-and-a-half years of brushing. But too much power may also be potentially problematic.Ī 2017 study published in the journal PLOS One found that electric toothbrushes were more likely than manual to abrade dentin-the tissue directly below the tooth’s enamel, which can become exposed when enamel wears away or gums recede. “If you get good checkups and your dentist is confident you’re doing a thorough job, you don’t need to change from a manual brush.”Įlectric toothbrushes can be very, well, powerful, which explains why they can do such a thorough job on plaque. That said, “You can brush very effectively with a manual toothbrush,” says Matt Messina, DDS, a consumer adviser with the American Dental Association (ADA). ![]() Plus, electric toothbrush users had healthier gums overall and retained 19 percent more teeth over the study period than those using a manual toothbrush. ![]() Here, researchers at University Medicine Greifswald, who followed 2,819 adults over 11 years, determined that using a powered toothbrush reduced the progression of periodontal disease. But the study authors say more research is needed to confirm that finding.Ī German study published in 2019 in the journal Clinical Periodontology also found that electric toothbrushes were more effective for gum health. In addition, the researchers found that oscillating powered toothbrushes (which have a small round head that rotates quickly in one direction and then the other) were slightly better at reducing plaque than sonic electric toothbrushes (which have an oval head that moves or vibrates rapidly from side to side). They also found that users of electric toothbrushes had a 6 percent reduction in gingivitis (gum disease) at one to three months and an 11 percent reduction after three months or longer. ![]() The researchers looked at 56 clinical trials of unsupervised toothbrushing by more than 5,000 adults and children, and found that study subjects who used a powered toothbrush showed an 11 percent reduction in plaque at one to three months, and a 21 percent reduction after three months or more, compared with those who used a manual toothbrush. One of the more comprehensive analyses of the topic-a 2014 review of studies by the independent Cochrane Collaboration-gave powered toothbrushes a slight edge at cleaning away plaque. NEED FOR SPEED 2015 CRACK HOW TOHere’s what to know and how to decide what’s right for keeping your pearly whites strong, clean, and cavity-free. When plaque builds up, it can cause tooth decay as well as gum disease. This helps get rid of bacteria that causes plaque, a sticky, germy film that adheres to teeth. Whichever you use, dentists agree that brushing your teeth for 2 minutes, twice a day, is the most effective step you can take for oral health. Which should you choose? Dental experts point out that each has its pros and cons, and that personal preferences and factors such as your age and general health might play a role in which kind of toothbrush is best for you. But you can spend more than $250 for a high-end “smart” electric toothbrush that syncs with an app on your phone and offers recommendations on improving your brushing technique. Those with rechargeable batteries (for which a single charge lasts anywhere from a few days to several weeks) start as low as $20. You can buy a manual toothbrush for less than a dollar, and basic powered models-which run on replaceable batteries-can be had for less than $10. There are, of course, cost differences between electric and manual toothbrushes. ![]()
