Sir I have a cavity in one of my teeth is there any effective home remedy for it regards

Ans: Hello
Any tooth which is decayed/broken should be treated as soon as possible. Regardless of whether it's hurting or not. Please remember that tooth decay if left untreated can spread to the neighbouring teeth.
Besides, even if the tooth is painless now it can trouble you later.
So please consult your dentist and seek his advice on what steps need to be taken

Ans: Hello,
First of all your dentist will have to determine the cause of the discolouration after a careful examination. Only then can he advise you how it can be corrected. You may have to get your teeth cleaned (Scaling and polishing) by your dentist. In some cases, bleaching may be necessary. Do consult your dentist.

Ans: If you're experiencing tooth sensitivity, consider consulting a dentist to determine the underlying cause and find the best solution.

Tooth sensitivity can be caused by various factors. Here are some common causes:

1. *Gum recession*: Exposed roots can cause sensitivity.
2. *Tooth decay*: Cavities can expose nerves, leading to sensitivity.
3. *Cracked teeth*: Cracks can allow bacteria to reach the pulp, causing sensitivity.
4. *Worn enamel*: Acid erosion or grinding can wear away enamel, exposing dentin. Aggressive brushing or using generous amounts of toothpaste can also damage enamel.
5. *Gum disease*: Inflammation and infection can cause sensitivity.
6. *Dental procedures*: Sensitivity can occur after procedures like fillings, crowns, or teeth whitening.
7. *Tooth grinding or clenching*: Grinding or clenching can wear away enamel and cause sensitivity.
8. *Acidic foods and drinks*: Consuming acidic foods and drinks can erode enamel.

Managing Tooth Sensitivity
If you're experiencing tooth sensitivity, consider:

1. Using a desensitizing toothpaste
2. Avoiding acidic foods and drinks
3. Practicing good oral hygiene
4. Visiting your dentist for a check-up and advice

Your dentist can help determine the underlying cause and recommend the best course of treatment.

Ans: Hello
At the age of 20, you're much too young to start losing teeth. I suggest you consult a dentist soon. It may still be possible to save the tooth with "the very large cavity" if you consult a dentist soon.
As for your other "very dirty" teeth, there could be external stains or deposits (called calculus or tartar - the result of inadequate or ineffective brushing) which can be easily removed. At worst, there could be multiple cavities caused by tooth decay which can also be restored with fillings or crowns.
Please note that a proper brushing technique and regular brushing will help keep your teeth healthy regardless of which brand of toothpaste you use.
