When you have had a root canal and have bad breath as a result, there are a wide variety of different things that you can do to solve the problem. First and foremost, you need to make certain that you do not use products to cover bad breath to begin with.
As it is difficult to brush over sensitive areas where you have recently had a root canal, using these products simply covers a worse problem. Brushing, especially after a surgery of this nature, is vital to ensure that you make your teeth as healthy and strong as they can be.
While you have had a root canal and suffer from bad breath, you must make the effort to continue brushing your teeth at least twice a day. If your standard toothbrush has bristles that are too hard for your sensitive teeth and gums, you should invest in a soft bristled Reach toothbrush to help you during this time. While you may only use it for a week or two, it is well worth the investment.
If you own a modular toothbrush, you will want to stop using it for a period of time and make use of a soft bristled manual brush to allow your nerves to become less sensitive. If you do this, and there is not an underlying problem causing your bad breath, you can make certain that your problem is quickly resolved without causing you discomfort.
