Why is the surface of my teeth not smooth anymore since I went for yearly cleaning?

The surface of your teeth may not feel smooth anymore after a yearly cleaning due to several reasons. Here are a few possible explanations:

1. Tartar Buildup: Tartar, also known as calculus, is a hard, calcified deposit that forms on teeth when plaque is not removed effectively. Over time, tartar can accumulate and cause the teeth to feel rough and uneven. Regular dental cleanings help to remove tartar and restore a smooth surface. However, if tartar has accumulated significantly, it may not be completely removed in a single cleaning, and the teeth may still feel rough until the next cleaning.

2. Sensitivity: Professional teeth cleaning involves the use of dental tools and instruments to remove plaque, tartar, and stains from the teeth. Sometimes, this process can cause temporary tooth sensitivity, which can make your teeth feel rough or gritty. Sensitivity usually subsides within a few days as your teeth adjust to the cleaning. If the sensitivity persists, talk to your dentist about desensitizing treatments.

3. Tooth Anatomy: The natural anatomy of your teeth can also contribute to the rough feeling on the surface. Some teeth, especially molars and premolars, have ridges and grooves called cusps and sulci. These anatomical features can create a naturally uneven texture on the teeth, which may feel rough to the tongue or fingers.

4. Incomplete Cleaning: In rare cases, a dental cleaning may not be thorough enough to remove all plaque and tartar, leading to a rough feeling on the teeth. If you feel that your teeth are still rough after a cleaning, discuss it with your dentist to ensure a proper and complete cleaning.

5. Dental Materials: If you have had dental restorations such as fillings or crowns, the surface of these materials may feel different from your natural teeth. Some materials, like composite resin fillings or porcelain crowns, can have a slightly rougher texture than enamel, which may be noticeable after cleaning.

It is important to note that the feeling of roughness on your teeth may be temporary and can improve within a few days or weeks after your cleaning. If the rough feeling persists or causes you significant discomfort, it's always advisable to consult with your dentist for further evaluation and treatment.
