5 Signs You Need a New Toothbrush

You rely on your toothbrush twice a day to clean your teeth. However, if you’ve neglected to replace your toothbrush when it needed, your oral hygiene efforts may be falling short. In some cases, a neglected toothbrush could be doing more harm than good. Regardless of the type of toothbrush you use or the stage of life you are in, it is important to recognize when your toothbrush has reached the end of its lifespan.

Here are 5 signs that you need to purchase a new toothbrush and throw your old one away:

#1 Your Toothbrush Has Frayed Bristles
If the head of your manual or electric toothbrush has bristles that are frayed, bent or broken, it is time to get a replacement. You can’t rely on a worn-out toothbrush to clean your teeth and gums properly. If you are brushing too hard these frayed bristles may happen sooner than the three-month mark.
#2 Your Teeth Don’t Feel Clean After Brushing
If you are confident in your brushing technique but fail to get that smooth and fresh feeling across your pearly whites after you use your toothbrush for two minutes, you may need to buy a new one. The removal of plaque, bacteria and food debris requires a well-functioning toothbrush.
#3 You’ve Been Sick
Most of our germs live in our mouths. If you have recently had a virus or other sickness, those germs likely migrated onto your toothbrush. To avoid re-infecting yourself every time you brush, we recommend replacing your toothbrush to stay healthy.
#4 Your Brush has a Foul Odor
It can generally be said that if something smells bad, it probably shouldn’t go in your mouth. A stinky toothbrush could be an indication of mold or bacterial growth. Treat yourself to a new one!
#5 You Can’t Remember When You Last Replaced It
A dentist will suggest replacing your toothbrush every 2-3 months, or when the seasons change (if that helps you remember). If you can’t recall when you last bought a toothbrush, it is probably time to part ways with your beloved oral hygiene tool.

At Peninsula Cosmetic & Family Dentistry, we help patients appreciate the role their toothbrush has towards their dental health and overall well-being.

No Insurance?
No Problem!

Join our Premier Plan Today

Dentistry should be as affordable as it is high-quality. At Peninsula Cosmetic & Family Dentistry, we firmly believe that the terms of a dental insurance plan (or lack thereof) should not dictate the quality of care our patients deserve. That’s why we are pleased to offer our in-house savings plan. Now, patients who are uninsured can STILL save on general, preventative, and even ortho services!

Absolutely phenomenal dental office. Not only are the dentists outstanding at their craft but, like every person in the office, they are incredibly friendly and genuine. And that is so important.
