Yes, it is a chemical change.
It is a reaction of lactic acid (acid produced by bacteria) and hydroxyapatite (mineral component present in enamel and dentin).
The tooth is rotting so it is changing its nature due to the influence of bacteria or the acid secreted by bacteria. If the new material is no longer dentine but the byproducts of decay then it is a chemical change.If the tooth breaks then that is a physical change.
It is physical. The tooth is broken into smaller pieces, but the pieces are still made of the same substances.
Tooth decay is a chemical reaction that occurs when acids produced by bacteria in the mouth (like Streptococcus mutans) break down the enamel and dentin of the teeth. These acids demineralize the hard tissues of the teeth, leading to the formation of cavities. The reaction involves the dissolution of calcium and phosphate minerals from the tooth structure by the acids.
You can tell if breaking a tooth is physical by experiencing pain, sensitivity to hot or cold temperatures, or noticing a change in the appearance of the tooth. Another sign is if you have difficulty biting or chewing with the affected tooth. It's important to see a dentist for an evaluation and treatment if you suspect a broken tooth.
Floride is added to toothpaste to strengthen the enamel of the tooth. This helps prevent tooth decay, particularly in children.

There are a few benefits from tooth bleaching. You will have an attractive white smile, but you have to be careful over-bleaching can cause decaying of the enamel. Without that your teeth will become very brittle.
See the problem either in Germany or at any place is the same,Improper brushing of teeth.When the food accumulates between the teeth it starts decaying and lead to to teeth decaying with it.
a hole forms in the enamel. it can be caused by many things. but decay begins and this hole progresses until it eventual reaches a nerve and becomes infected.
It is physical. The tooth is broken into smaller pieces, but the pieces are still made of the same substances.
a chisel shaped tooth is a tooth that is sharper than your other teeth. an example of a chisel shaped tooth is your incisor.
Damage to your teeth or tooth wear can be caused by any process that results in loss of integrity of the tooth surface. Tooth decay is a bacteria-caused form of tooth damage. The other forms of tooth damage are the result of mechanical or chemical assault to the tooth structure which may be brought about by your daily habits for example grinding in your sleep and tooth brushing. Acquired tooth wear can be classified into attrition, abrasion, erosion, abfraction and fracture. http://www.intelligentdental.com/2010/02/20/how-your-daily-habits-can-hurt-your-teeth/

Fluoride is the chemical added to many municipal water supplies to help prevent tooth decay.
