WORDS PANK JIT SIN
If you are like everyone else who practices good dental hygiene, you’ve probably brushed your teeth this morning. Which toothbrush did you use? It is safe to assume most of us use a manual toothbrush. I recently went for a regular dental checkup and was told my gums were receding. My dentist advised me to get an electric toothbrush as it would prevent my gums from receding further. Having recently seen a video of how manual toothbrushes were better at removing dirt than electric ones, I was somewhat confused. So, what does a good writer do? We do some research. Here’s what I found.
Electric may be better
According to a scientific review, which looked at 51 studies with about 4,600 participants, electric toothbrushes are capable of significantly reducing plaque over short- and long-term use.1 Similarly, electric toothbrushes reduce the risk of gingivitis more than manual toothbrushes in the short and long term.1 However, as it is a review of existing studies, the strength of the review was considered to be of moderate quality. This means it isn’t a foregone conclusion and further research may change the situation. For now, it looks like electric toothbrushes are better than manual ones.
It can get a little confusing though, as not all electric toothbrushes are equal. There is a difference even within electric toothbrushes. It appears that electric toothbrushes that oscillate and rotate (makes circular motions) are better at cleaning plaque than those that create side-to-side movements.
I asked Dr Catherine Chong, a dentist in private practice, on how to determine which toothbrush is better. According to Dr Catherine, electric toothbrushes are indeed better. However, some people do just as well with manual toothbrushes. She recommends the use of plaque disclosing tablets to determine which toothbrush is more effective for an individual person. She says a person can perform a simple test of using a manual toothbrush to clean their teeth and then using the tablet to check for plaque remnants. Then the next day, the person can try brushing their teeth with an electric toothbrush and testing with the plaque disclosing tablet again to see the amount of plaque left after brushing. The difference will allow the person to decide which is best for him or her.
DID YOU KNOW?
Plaque disclosing tablets are chewable tablets that stains plaque on teeth. It is usually made of vegetable dye that makes the plaque stand out and is either red or blue in colour. Although it isn’t a common item, these tablets can easily be purchased online.
Manual toothbrushes are much cheaper than electric toothbrushes. They usually range from a few ringgit to tens of ringgit, depending on their unique selling points. Generally, toothbrushes are divided into soft, medium and firm bristle types. But within these three types are the numerous designs, angles, and materials that go into the bristle production.
How about the measurements of the toothbrush and bristles? A Korean study says the length of the bristle head should be 2.14 to 3.05 cm for men and 2.09 to 2.96 cm for women. The length of bristles should be 1.07 cm for men and 1.03 cm for women. The width of the toothbrush head should be 7.7 mm. Finally, the neck of the toothbrush should be 3.13 cm for men and 3.0 cm for women.2 While the study was done on Koreans, they should not stray too far from our measurements as they are also Asian in terms of size.
While this may sound confusing, the best advice would be to test out a few types of toothbrushes and find out which one fits you the best.
Electric toothbrushes are less common but are seeing better uptake in recent years. As mentioned earlier, some models oscillate and rotate while others only move in a singular side-toside motion. While the hard work of manual brushing is already done by the motor of the toothbrush, the highspeed movement and vibration of the device can still cause damage to gums and teeth if the user is not careful.3

Specific types of toothbrushes
Beyond the usual round or oblong toothbrush heads we are used to, there are some uncommon types in the market. First is the interdental toothbrush, which is good for cleaning between teeth and dental braces.
We also have end-tufted toothbrushes which are specially made to clean the wisdom tooth area and also crooked teeth with odd angles that are hard to reach using normal toothbrushes.
Whichever toothbrush you choose, remember it doesn’t negate the recommended twice-yearly visit to your dentist. Regular visits to the dentist not only ensure your teeth and mouth are in good condition, it will also help doctors detect abnormalities early. These includes receding gums, oral cancers, dry mouth, fungal infections, and taste impairment.
A dentist also trained to look at the muscles of the head, neck, jaw, tongue, salivary glands, and the nervous systems of the head and neck. They can quickly refer the patient to a specialist if they suspect there is something serious going on. HT
