How to Choose the Right Brush Head for an Electric Toothbrush?

Virgil Flores

I have tried to quit sugar and carbonated drinks countless times because I've already had two decayed teeth. However, I couldn't resist the temptation, ending up in failure each time. 

Now, after eating sweets or drinking a cola, I gargle or brush teeth to ensure my dental health.

On the Internet, there are a lot of popular science articles about how to choose the right mouthwash or electric toothbrush, but it seems that few people know how to choose the brush head for an electric toothbrush.

Many people think that they should consider the size and stiffness of the brush head. However, how to choose a brush head is as complicated as purchasing an electric toothbrush. How can we know the pros and cons of the brush head for an electric toothbrush? Read this article, and you'll get the answer. 

1. Brush materials

Generally, for comfort and convenience, the brush head is made of soft materials, including natural and nylon bristles. Most traditional manual toothbrushes consist of natural bristles which promote the reproduction of bacteria. 

However, nylon bristles are different because they are non-absorbent. Wear-resistant, slim and soft, nylon bristles bend well and recover fast, great for massaging the teeth. Therefore, nylon is the best material for the brush head of the electric toothbrush.

For another thing, you should consider the stiffness of bristles. There are two common types: medium brushes and soft brushes. Medium brushes clean the teeth well, but they also abrade them; moreover, using them with too much force leads to damage to the gums. The soft brush head is better for the teeth and gums, but it's easy to wear out, remove thick plaque less effectively.

For ordinary people, especially children, it is recommended to choose soft brush heads; for people who have the habit of drinking coffee or tea, their teeth are stained, so medium brush heads are suitable for them. However,  you'd better select a brush head that is treated well to prevent sharp edges from damaging the gums.

 

2. Brush Shapes

There are many shapes of brush heads on the market, including cylindrical, diamond, triangular, etc. Theoretically, diamond and triangle shapes result in a better cleaning effect, because they have edges that can reach deep interdental space and clean more plaque.

The arrangement of brush bristles also varies in flat-trim, multilevel trim or V-shaped. A proper structure of the brush head will bring you a better cleaning effect. Only the brush head that has high cohesion and the largest possible cleaning area, as well as ideal cleaning depth, can make the best use of itself for effective cleaning.

 

3. Bristle density

The brush bristle number in a unit means the bristle density. The higher the density is, the larger the contact area will be, so the better the cleaning effect will be. 

The material, shape, and bristle density of brush heads are not completely irrelevant, but interrelated. For example, compared with a cylindrical shape, a diamond brush head saves space and increases the bristle density, affecting the number of brush bristles.

 

4. End-rounded bristles

End-rounded bristles play an important role in gum protection. Generally, the bristles of quality brushes must be fairly rounded, because the surfaces of non-end-rounded bristles are mostly irregular and sharp; in comparison, the end-rounded bristles have a curved surface. 

Therefore, the amount of end-rounded bristles is also a key indicator for judging the quality of a brush head. According to the electric toothbrush standard, the percentage of end-rounded bristles of the electric toothbrush head for adults requires not less than 50%, while that for children requires over 70%. 

If you use an electric toothbrush with a low percentage of end-rounded bristles, it will damage the soft tissue in your mouth and cause damage to the surface of teeth, what's worse, you will not achieve good cleaning effect.


The brush head I have been using for a long time is this one from Alfawise, and I have been repurchasing it several times.

Alfawise brush head is very comfortable. Because my teeth and gums are very sensitive, and I use it for a few months without damaging gums and oral mucosa. The design is considerate.

The wavy shape design of this brush head can fit most people's teeth shape. At least for me, I feel the hidden seams thoroughly cleaned. I used the brush head twice a day, and I haven't had swollen gums for a long time.

I am not exaggerating! I like to rub my teeth with my tongue gently after brushing my teeth. How smooth and how clean they are!

By the way, you can get three brush heads, and each one has a ring in a different color as a distinction, so you won't mix them up if you use them with your family.

If you buy them for yourself, I suggest that you change a brush head every 2 - 3 months. After all, there will be more and more bacteria as time passes.

Honestly, these brush heads are for a total of nine months at the cost of only $3, and is there a more exciting price?
