Hello Don’t worry stay positive and go ahead sooner the better you must be fine take care

Dentist or doctor are there to help to you. Getting afraid of your doctor is common but to help you I can only say that if you visit your doctor regularly then chances of getting bad diagnosis is very unlikely. Infact in developed countries where regular health checkup is done after every 6 months helps in early diagnosis which in turn helps to prevent further problem. Lastly it's better to be sure than to be in doubt. Donot let your fear build a home in your head permanently.
