My Dentist suggested ClassV Restoration for some of my teeth. Is there a medicine alternative to the same?

Ans: Hi Ashish
You need to consult a Periodontist (a dentist who specialises in gum problems) or your general dentist. Only after a proper evaluation can the remedy be suggested. But most gum problems are treatable

Ans: Hello
By "not so strong" do you mean that your teeth are more prone to decay (cavities) and chip off easily?
If so, your teeth could be deficient in Calcium. I'm assuming you have always maintained good oral hygiene. Unfortunately calcium supplements taken after childhood do not help as tooth formation is already complete by then.
You might benefit from using certain special toothpastes which claim to remineralise teeth. But, in general, it means you need to take extra care with your rinsing/brushing/flossing to keep your teeth healthy.
If by "not so strong" you mean your teeth are shaking or you cannot confidently bite something hard, the fault lies not in your teeth but with your gums and supporting structures. Weak or infected gums can be easily treated. Please visit your dentist so that the problem can be diagnosed and appropriately treated

Ans: Hello,
Please visit your dentist for a basic consultation. If the enamel of your teeth has worn away due to acidic erosion or excessive abrasion he will likely recommend a suitable desensitising toothpaste.
If you suffer from hyperacidity or acid reflux please consult your physician for proper guidance

Ans: Hello Venkatesh
Please consult your dentist.
In my opinion gum polyps cannot be treated with medicines alone. They may require surgical removal. Please do not be intimidated. It's a very, very minor procedure.
Also the cause has to be identified and suitably treated to prevent recurrence. So please do not rely on home remedies or medicines alone.
