Pulpitis usually requires root canal treatment, which varies in cost depending on the location of the tooth, and also varies in cost depending on the level of the hospital. In general, in tertiary hospitals, the cost of single root canal treatment for anterior teeth is about $300-400, while double root canal for premolar teeth is about $500, three root canals for posterior teeth is about $700, and four root canals is about $800. Developing good oral hygiene habits is an important measure to prevent pulpitis, and you should at least brush your teeth properly after meals and before going to bed.
