you're not screwed. I've been dealing with holes in my teeth for 27 years. Honey/garlic ferments and hydrogen peroxide and aspirin powder have taken care of any problems I have ever had. Keep you teeth clean the best you can. If an infection does occur, it's not the end of the world. The honey/garlic is an excellent antibiotic. Aspirin powder worked directly into painful areas with your tongue will stop pain. Hydrogen peroxide mouthwash before bed will clear the infection. Is it a life long battle? yes. Can you do it? yes, absolutely. If you can afford a good dentist, by all means see one. If not, there are still ways of dealing with issues.
