What are the ways to treat black spot in teeth?

Hello,

Welcome to icliniq.com.

I understand your concern. The most common cause of black spots on tooth is cavity or tooth decay. Unfortunately, there is not any medicines or home remedy that could stop the progression or cure tooth decay. This can only be done by a dental treatment. Tooth has three layers, outer enamel, dentin and innermost never layer. When decay starts in the enamel layer, it does not show any symptoms other than visible black spot on tooth. At this stage, a simple tooth filling can be done. But if left untreated, it progress through dentin and when reaches nerve layer it starts to give out pain. This is when a simple filling cannot be done. A root canal treatment and crown procedure will be the only option to save the tooth in that stage.

I can understand your situation but please visit the dentist and get a simple filling done as soon as possible to save that tooth. Treating at early stage will be a good decision financially. Meanwhile avoid stick and sugary foods and maintain a good oral hygiene to reduce the decay from rapidly progressing. I hope this helps.
