A cat’s teeth will not grow back after they are broken. When a cat is in the teething stage when it is young, its teeth are broken, and the roots of the broken teeth will be replaced by new ones. If the cat is about one year old, the broken tooth will require surgery to extract the remaining tooth root. ​​​​​​

Try not to get your cat’s teeth injured or broken. The growth and replacement of a cat's teeth are very regular. By observing the cat's teeth, you can often roughly estimate the cat's age. Generally, cats that are three to four weeks old will have primary canine teeth and small incisors on the upper jaw. By the fifth week, all primary teeth will have grown.
