I chipped the back part of my upper second molar. The dentist said I needed a and a crown for the tooth. I cannot afford these for now and my dental insurance is already used up for the year. Can I leave the tooth untreated until January next year? The tooth is slightly in pain but painkillers can manage it. I have been using Sensodyne for the sensitivity, which is working great so far. What should I do to keep the tooth from being infected? What other treatment methods can you suggest aside from canal and crown? I would be thankful for your help!
