5 Common Toothbrushing Mistakes to Avoid

5 Common Toothbrushing Mistakes to Avoid

Brushing your teeth twice daily is a good start, but it’s all for naught if you’re breaking these cardinal rules of oral care. Here are some expert tips on how to identify and correct common toothbrushing mistakes.

Worried about your brushing technique? You’re way ahead of the curve. Around 31% of Americans don’t brush their teeth the recommended two times per day, and 2% skip the habit altogether. 

While we’re glad you’re not among those neglecting their oral health, there are a few faux pas you can make that may be doing more harm than good. 

Join our team at Rifkin Dental in Carmel and Yorktown Heights, New York, as we explore a few tooth-brushing mistakes (and how to avoid them). 

1. You haven’t replaced your brush in a while

This first mistake has nothing to do with your technique and everything to do with the lifespan of your brush. 

The bristles may appear to have some life left in them, but we recommend replacing your toothbrush every 3-4 months. A good way to remember is to change it with the seasons. 

We’re adamant about this one because your brush gradually becomes less effective, and frayed or broken bristles just don’t clean as well. 

2. You’re cutting it short

You should brush your teeth for two minutes every session — most folks don’t make it past 45 seconds. Two minutes isn’t an arbitrary number. It’s the amount of time that ensures you’ve removed as much built-up plaque and food as possible. 

Keep yourself accountable with a timer or an electric toothbrush with one built in. 

3. You think harder is better

Vigorous scrubbing with stiff bristles may sound like the best approach, but we prefer softer bristles with firm but gentle motions. 

Hard bristles may be better at stain removal and denture cleaning, but soft bristles do plenty when it comes to removing plaque and food. In fact, everyday use of a hard-bristle brush can actually damage your enamel and gum tissue. 

If you’re not sure whether your brush is right, head to the store today and look for one labeled “soft” or “medium.” If you have more questions, don’t hesitate to bring your oral hygiene tools to your next appointment and let us take a look. 

4. You forget about the rest of your mouth

Brushing your teeth isn’t just about your teeth — it’s about your whole mouth. You need to hit every area of your teeth, including down to your gum line and the surfaces that face your tongue. You should also give your tongue and cheeks a good scrub down, since bacteria hang out on your tongue just as much as on your teeth. 

5. You’re brushing at the wrong times

It’s common to think that brushing right after eating is a good idea, but you could be missing out on a natural process that actually supports your oral health. Brushing right away (especially after you eat acidic foods) actually rubs acid deeper into your teeth, leading to erosion and enamel damage. 

Instead, allow your mouth at least 15 minutes to produce acid-neutralizing saliva and give yourself the best overall clean. 

Above all else

Even those with the best technique, the best tools, and the best timing need one thing: professional support. 

Our hygienists and expert dentists can reach areas your toothbrush and flosser can’t and make sure no plaque survives. We can identify any areas of your routine that need adjusting and support you in making those changes.
