I used to neglect my dental hygiene when I was younger, which of course is causing me remorse now, especially that I know about mewing.

I visited a local dentist and one of my teeth seems to be in a bad condition and would need root canal treatment. She said that there is some hope on that I could survive without any special treatments, but it is unlikely. Of course I'm now eating healthy, drinking only water and brushing, flossing and using mouthwash daily. Based on what I've read, If that treatment will get done, I will have to get a tooth implant in like 8-10 years.

I know it will at least somewhat affect my mewing gains. My main question is just how much does this affect them overall? Has anyone here gone through a situation like this? All help is appreciated.
