The usual way for brushing teeth is effective when you have seemingly perfect teeth, and 30 seconds of brushing is ok. But if you have crooked and missing teeth 30 seconds and normal routine just won’t cut it; you can actually make your teeth a lot worse by not taking care of your teeth by effective brushing.
So what about mouthwash, is these going to fix the problem?
Actually no and yes; mouthwash has been linked with oral cancer, and should not be used to replace brushing; it has some health benefits though with removing bacteria, but should be used in conjunction with good hygiene habits.
So what about standard brushing?
If you brush too hard you will probably do more harm than good, so be efficient not rough. Also if you’re going to be brushing your crooked teeth, you may find that you will also need to use dental floss to get between the gaps of your teeth to remove bits of food; sometimes you will have overlapping teeth though and flossing will become a real chore when trying to get the angles right for the dental tape/floss.
It’s probably best to get invisalign treatment to straighten your teeth if they are too crooked or badly aligned; that will cost money and take time, but well worth it in the long run, and getting it done will make your nightly/morning routines easier.
Get a good toothbrush, with medium soft bristles, and an electric toothbrush in conjunction with that; sonic usually works better, but cost more though.
Conclusion: Use regular brushing in conjunction with an electric toothbrush to prolong the life of the electric toothbrush heads; brush with the normal toothbrush, and use the electric one after rinsing to get the bits you missed between your teeth from regular brushing. If you are comfortable with using dental floss/strips then use them too if need be.
