You should replace your toothbrush after three months.
Manual toothbrushes become worn out after about 3 months and are not as
effective as they once were.
The two most popular brands of manual toothbrushes are Oral-B and Colgate. These companies pretty much control the market when it comes to manual toothbrushes. You can learn about their different manual toothbrushes at these websites: http://www.oralb.com/products/manual-toothbrushes/ and http://www.colgate.com/app/CP/US/EN/OC/Products/Toothbrushes.cvsp.
The main advantage of manual toothbrushes is the cost. They are much
cheaper than electric toothbrushes. Whereas an electric toothbrush can cost you
$50-$100, manual toothbrushes can be bought for just a few bucks. Another
advantage is that manual toothbrushes come in different sizes and colors, so
there's a larger variety to choose from.
According to the Oral-B's website, manual toothbrushes should be replaced every 3-4 month because the bristles tend to become less effective for cleaning.
The main downside of electric toothbrushes has to be their cost! They are much more expensive than the manual toothbrushes and typically cost between $50 and $70. In addition, the heads of the electric toothbrushes must be replaced every three months, adding to the cost.
Electric toothbrushes are an excellent tool to keep your teeth clean and
healthy. They offer many advantages:
•
They allow you to remove plaque more efficiently and
quicker than manual toothbrushes.
•
You don't need to brush hard in order to get good
results. This means that you are much less likely to injure your gums.
•
People who suffer from physical conditions like
arthritis find electric toothbrushes as a great replacement to manual
toothbrushes because they are easier to grip and you don't need to use as much
physical power to get your teeth cleaned (the powered brushes do the cleaning).
• It is more fun to brush with electric toothbrushes compared to manual toothbrushes, especially for children.
