Did you know that the toothbrush you’ve been using for the past six months is likely well beyond its expiration date? No need to feel ashamed. Most people don’t. In general, many like to go by the social rule, if it isn’t broke, don’t fix it. However, when it comes to proper oral care and teeth cleaning, science overrules social opinion. 

When to Replace Your Toothbrush

According to the American Dental Association (ADA), and the Centers for Disease Prevention and Control (CDC), toothbrushes need replacing about every 3-4 months. 

As family dentistry in Newbury Park, we witness how a lack of teeth cleaning care by not replacing your toothbrush can lead to severe oral issues. As recommended, we suggest not only replacing your toothbrush after 3-4months but to also to replace it if: 

The Bristles Fray 

When first purchasing a toothbrush, whether, with soft, medium, or hard bristles, they all are sturdy and able to get into the crevices of your teeth. Over time, when the bristles fray, they are not equipped for teeth cleaning or teeth whitening. Frayed bristles may lead to build-up as they are not firm nor straight enough to remove plaque. 

Electronic toothbrush heads may need replacing a bit sooner, averaging around 12 weeks max. Although many electric toothbrushes are great for thorough teeth cleaning, the constantly rotating and vibrating, especially with shorter bristles, make it easier for them to damage. 

If you see that your bristles are turning out, bending, or look worn down, we suggest purchasing either a new toothbrush or toothbrush head for proper teeth cleaning. For in-depth cleaning, schedule a dental checkup with Newbury dental. 

Have a Cold or Illness

Unfuately, toothbrushes do not kill off bacteria or viruses. Instead, bacteria can latch onto the bristles and collect germs. If you are sick or have overcome sickness, we highly suggest swapping your toothbrush head or buying a new toothbrush to prevent intaking bacteria. Even if the toothbrush was new, safety comes first. We instead have a healthy smile than just white teeth, for teeth whitening is always an option.

Protect Your Toothbrush 

A toothbrush cover can cause mold, so we suggest protecting your toothbrush by storing it in a safe place like your cabinet or at least positioning your toothbrush furthest away from your toilet. 

Invest in a High-Quality Toothbrush 

We all like to save money, especially on something as little as a toothbrush. However, choosing a high-quality toothbrush is essential for proper teeth cleaning. Investing a bit more cash or time to picking a great toothbrush can save you money in the long run as the bristles may last much longer. Remember, it’s quality over quantity when it comes to essential teeth cleaning.
