Ans: Hi
External stains are usually caused by food colours in the food or beverages we consume on a daily basis. She should try to identify and cut out the offending item from her diet. And, of course, brushing after every meal helps.

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: 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
Dark stains on front teeth can be caused by various factors, including:

1. Poor oral hygiene: Inadequate brushing and flossing can lead to plaque and tartar buildup, causing stains.
2. Coffee, tea, and wine consumption: Chromogens in these beverages can bind to tooth enamel, causing discoloration.
3. Tobacco use: Smoking or chewing tobacco can cause significant staining.
4. Trauma or injury: Blood from the injury can seep into the tooth, causing discoloration.
5. Medications: Certain medications, like tetracycline and doxycycline, or iron supplements can cause tooth discoloration as a side effect.
6. Other factors include enamel hypoplasia (caused by a deficiency of Calcium) or fluorosis (caused by exposure to an excess of fluoride during the tooth developmental stage)

To address dark stains on front teeth, consider the following options:

1. Professional scaling and polishing. In severe cases teeth whitening or bleaching may be necessary.
2. Dental bonding or veneers
3. Enamel microabrasion (for fluorosis or enamel hypoplasia)
4. Improved oral hygiene habits
5. Avoiding stain-causing beverages or using a straw
6. Quitting tobacco

Consult a dentist to determine the best course of treatment based on the underlying cause and severity of the stains.

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.
