I don't know why one dentist would say something, while another one does - sometimes it's because they don't want to scare you away or alarm you. Maybe your 1st dentist left it up to his dental hygienist to discuss the matter with you. Did you ever ask your 1st dentist about gum recession? Electric toothbrushes have been found to be more thorough with their plaque removal on hard-to-clean tooth surfaces. They usually have soft or extra-soft bristles (very important), and some of them have pressure-sensors that change the pace of the brushing, when it senses that you are pushing/brushing too hard.
Note: no ones gumline "wears away" just because they are brushing too hard though. You may damage and irritate your gums, but they won't recede from the occasional hard brushing.
If you've experienced gum recession, it is due to:
1. Periodontal disease (loss of supportive bone around the roots of your teeth, under the gums)-caused by bad bacterial infecting the pockets surrounding those teeth.
2. Inflammatory responses of your body, where your immune system over-reacts to damage/infection. This has a genetic (inherited) component, and an "epigenetic" (affected by diet, sleep and stress) component.
It is not possible to brush your teeth well with a manual toothbrush without brushing your gums at the same time . However, it is possible to accomplish this goal without hurting your gums with a Braun Professional Toothbrush. There are only 3 brush heads that I recommend using. Please see my video on Youtube at the link below for a more detailed explanation of how to use a Braun toothbrush and don't forget to floss twice a day.
Thank you and have a great day!
As the gums recede, the root is exposed. There is no hard enamel on the root; in fact, it is much softer. Extra vigorous brushing over the root will actually wear away the exposed root and create a ditching effect, which itself can contribute to more recession. Yay.
So always use a soft toothbrush and start your brushing at the gum line and work away from it. Don't brush up and down or use the toothbrush like a scrubbing brush. More is not better- sometimes more is just more- and it will cause a problem.
If scrubbing and over brushing are not the problem, then investigate a clenching and grinding problem. Perhaps you might benefit from a night guard to prevent the problem when you are sleeping.
Also be aware that sometimes you may have had recession for a long time but it is stable. Perhaps the previous dentist noticed that and did not record any changes, so there may not have been a good reason to address it with you. A new dentist, not knowing your history, may be going only.
Dentist do vary; some are more focused on decay, others the gums still others, the overall bite/lesions. We try to catch everything. We are human. I have seen excellent results from plaque build-up with electric toothbrushes.
To avoid further damage you and your Dentist need to explore the reason behind your issue, resolve the problem (electronic tooth brush that automatically stop if excessive pressure is applied during brushing), a guard or what your dentist recommends. Remember you and your Dentist should be team working together.
Regarding the wear on teeth and gum receding, there are multiple reasons including tooth brushing heavily, hard bristle brushing, occlusion problems, bite related issues, thin gum tissues, positioning of teeth in the arch, crowding and more. Your treating dentist shall evaluate and give you more appropriate reasoning for the situation you may have.
And remember it's not how hard and how fast you brush... But rather the quality of your brushing and how long as well as how frequent
