How Often Should You Replace Your Toothbrush?

Updated on December 9, 2016

Keep Your Teeth Clean and Healthy

Choosing the right toothbrushes is one of the most important things in oral care in order to keep your teeth clean and healthy. Many people will use the same toothbrush for several months long after it is really useful. The statistics from the typical purchase rate shows that one toothbrush is bought per person per year. Since the accuracy is what is needed, it follows that as soon as the toothbrush bristles have become bent, you no longer can aim the bristles properly at the back areas of the tooth.

Average Brushing Time is 3 to 10 Minutes

With average brushing taking 3 to 10 minutes each time, the useful life of a toothbrush is usually less than a month. It is therefore advisable to buy several toothbrushes for each member of the family to store. This way you can throw away to the nearest dustbin any which are worn out, and not hang on to them because you forgot to include them in your shopping list.

Factors to Consider When Choosing a Toothbrush

There are several factors you should consider when choosing a toothbrush but the main ones are:

  1. The head of the toothbrush should be small so that you can manoeuvers it easily in different angles
  2. Choose toothbrushes with nylon rather than natural bristle. Toothbrushes with nylon bristles are cheaper, last longer, dry out faster and do not become soft as those toothbrushes with natural bristles.
  3. Do not choose toothbrushes labeled soft unless the toothbrushes are for young children or you have been instructed to do so by a dentist. The toothbrush bristles need to be rigid to dislodge plaque. Hard bristles will be better for you.

Follow the three rules and choose the cheapest toothbrush you can find, but buy plenty of them.

Choose Toothpaste

Now that you have chosen a toothbrush, the next thing you need is to choose toothpaste. Choose toothpaste with fluoride. This is because fluoride has a significant decay reducing effect. This decay reducing effect is as much as 30 percent. Introduce your children to toothpaste as early as it is possible so that you can minimize chances of your children having decayed teeth. For the adults, brushing your teeth with good toothpaste and fluoride toothpaste will reduce secondary decay around fillings as well as root decay. Good toothpaste will make your mouth feel fresh after you have brushed.

Antiseptic Mouthwashes

There are no shortcuts to good brushing of teeth. Among many people, there is a belief that antiseptic mouthwashes are a good substitute for the toothbrush and toothpaste. This is not true as most mouthwashes have little effect beyond giving your mouth a fresh feeling. Mouthwashes with chlorhexidine are worth a try as chlorhexidine is partially effective against plaque bacteria. But rather than using chlorhexidine mouthwashes on a daily basis, just use it once a week and the rest of the days clean your teeth using a toothbrush and toothpaste.

        As a CDA, I can tell you that hard toothbrushes are the worst kind of toothbrush you can buy; people tend to scrub, which is not necessary, and using a hard toothbrush causes tissue trauma as well as tooth erosion overtime. Soft toothbrushes ARE in fact the best tooth brush to buy. If you brush appropriately, at a 45 degree angle into the gum line with short low pressure pulses twice a day, where the plaque "lives", in addition to having a proper flossing regime your teeth and gums will stay clean.
