It is due to improper brushing technique and poor oral hygiene

Yellowish stains on teeth can have various causes, and it's best to consult a dentist for an accurate diagnosis and appropriate treatment options. potential causes and treatments: Food and drinks: Consumption of certain foods and beverages, such as coffee, tea, red wine, and certain fruits, can lead to tooth staining over time. The pigments in these substances can gradually accumulate on the enamel, causing discoloration. Regular brushing and professional cleanings by a dentist or dental hygienist can help remove surface stains. Poor oral hygiene: Inadequate oral hygiene practices can result in the buildup of plaque and tartar on the teeth, which can contribute to tooth discoloration. It's important to brush your teeth at least twice a day, floss daily, and visit your dentist for regular cleanings to maintain good oral hygiene. Tobacco use: Smoking or chewing tobacco can cause yellowish stains on teeth due to the chemicals and tar present in tobacco products. Quitting tobacco use can help prevent further staining and improve oral health overall. Age-related changes: As we age, the enamel on our teeth naturally wears down, revealing the underlying dentin, which has a yellowish hue. This can lead to a more yellow appearance of the teeth. However, proper oral hygiene practices can still help maintain a healthy and attractive smile. The specific treatment for yellowish stains on teeth depends on the underlying cause and the extent of the staining. Your dentist may recommend professional teeth cleaning to remove surface stains or other treatments such as teeth whitening procedures, dental bonding, or porcelain veneers to address more significant discoloration.

Hello It is due to poor oral hygiene and wrong technique of brushing

Looks like localized gingivitis. Maintain oral hygiene. Warm saline rinses thrice a day. Visit a local dentist for physical evaluation and treatment (if required).

Due to vigorous brushing. Apply Metrogyl’s Dj gel 3-4 times daily

You have high frenal attachment in between your lower central incisors. Your frenal attachment is rather very close to the tip of the papilla. The frenulum is a small fold of tissue that connects the lips to the mucosa covering the jaw over it. A high frenal attachment in between lower teeth generally leads to recession that is progressive in nature and in upper teeth it may cause diastema (spacing) in between upper incisors. Please get your upper incisors checked too as i see some gap in between your upper central incisors. But, if you are not facing any issues in upper teeth, just let it be then- nothing to be done. You may have some subgingival calculus too as i see mild gingivitis. Recession in your canines (lower both sides) could be attributed to their buccal placement in the arch. So, don't brush too vigorously or use a hard tooth brush (although you have mentioned using an electric brush, still, don't be too vigorous).

Hi. It's due to deposits and improper brushing.
