How Often Should I Replace My Toothbrush?

When was the last time you replaced your toothbrush? We throw out expired foods, restock vitamins and supplements, and replace our beauty products often, but when it comes to health and beauty, it is our dental hygiene that does not get as much attention or thought as other areas of our regimen. However, there are important rules and tips you should follow for maintaining optimal dental health.



When To Change Your Toothbrush


Most dentists recommend changing your toothbrush every 3 months. Overtime, toothbrushes go through normal wear and tear and become less effective with removing plaque from teeth and gums. Studies have found that around 3 months is when the bristles break down and lose effectiveness. 


One other consideration we do not typically think about (and probably do not like to think about) is that germs can hide and build up in toothbrush bristles. This makes it important to replace your toothbrush after you have had a cold, or risk possible infection. 


"Fungus and bacteria can also develop in the bristles if not taken care of properly. After use, make sure you rinse off and dry your toothbrush thoroughly, storing uncovered in an upright position and keeping it away from other used toothbrushes. When traveling, be sure to cover your toothbrush head to protect it and reduce the spread of germs.


If you can't remember exactly how long it has been, pay particular attention to the condition your toothbrush head is in - whether the bristles are worn out, fan out, or frayed, or especially if you see dark colour changes, which is a sign of mold.



What Happens If I Don't Chang My Toothbrush Often Enough?


If knowing that bacteria and fungus accumulates on your toothbrush bristles overtime is not enough reason to replace your toothbrush more often, there are also a number of other risks and uninviting issues involved with not replacing your toothbrush. One risk includes damaging your gums, as old toothbrushes become ineffective with removing plaque from your teeth, which leads to gingivitis. Left untreated, gingivitis leads to infection, which can cause teeth to fall out.


Even more unappealing, you can get sick from overused toothbrushes (see:bacteria and fungus build up), your toothbrush can grow mold, or possibly the least appealing, you can ingest unwanted particles if stored near a toilet. 


I do not know about you, but i am going to change my toothbrush right now and schedule a deep cleaning with my dentist.



What To Consider When Shopping For Dental Products


Ask your dentist during your next dental checkup and cleaning for recommendations about what you should be buying based off your individual needs, your particular dental health state, etc.


Some common suggestions among dental professionals are to look for toothbrushes with soft bristles, as hard bristles damage your teeth and gums, choose a toothbrush head size that touches one or two teeth at a time, use a toothpaste containing fluoride approved by the necessary dental association, consider using mouthwash to further fight plaque and gingivitis, and do not forget floss!


Consider investing in an electric toothbrush, as these have been proven to improve oral health beyond what a manual toothbrush can do by removing plaque, reducing gingivitis and eliminating teeth staining. They have also been shown to minimize the amount of plaque on the teeth of people with periodontal disease. 


Do your research on what products fit your needs best, and do not forget to ask your dentist for recommendations.
