If you have hard to reach places in your mouth that a conventional toothbrush just can’t reach, then it may be time to consider an electric toothbrush.
There are various types of electric toothbrushes, such as battery powered, mains chargeable standard or sonic.
With the battery powered toothbrush it does the job fairly well and you can have an all round clean feeling, and it can get into the hard to reach places, and gaps of your teeth, but generally it lacks the power to clean the teeth with gaps effectively.
If you get a mains chargeable toothbrush that’s similar to the battery version, just with more power and better oscillation you will get some good results and at best it will be quite effective at cleaning your teeth.
A sonic toothbrush usually costs more than the battery and the chargeable toothbrushes combined, but it can really clean deep and help prevent tooth decay from stuff stuck in the teeth that might not brush away with normal, or standard from an electric toothbrush. Though if you have sensitive teeth it’s best to stick with the non-sonic electric, or battery powered toothbrush.
