How many teeth?

There are so many questions when it comes to teeth. We’ve noticed recently that many of you have searched for ‘How many teeth do adults have?’, ‘How many teeth do children have?’, ‘Have many teeth do sharks have?’, and so forth. So, we thought we’d answer some of your most frequently asked questions on ‘How many teeth’.

How many teeth to adults have?


There are 32 adult teeth in total. The last four of these teeth are called wisdom teeth. These four teeth usually appear later than the rest, generally between the ages of 17 and 21. Not everyone will have all four wisdom teeth appear in their life. Some lay dormant and may not even come through to the surface.

If you are worried about a wisdom tooth, please call us on 020 7236 3600 to book a check-up. One of our award-winning dentists can take X-rays of your teeth and let you know any plan of action you may need to take when it comes to wisdom tooth pain or worries.

How many teeth to toddlers have?


Did you know that babies’ teeth start to develop before they are even born? With that being said, most teeth do not actually come through until they are around six to twelve months old.

Most children have a set of twenty milk or baby teeth by the time they are three years old. When they reach the age of five or six, these milk teeth will start to fall out to make way for adult teeth.

Many of our patients ask us the same question quite often, and that is ‘When should I bring my child to the dentist?’. The simple answer is, as soon as they have teeth (this is around the 18-month mark). This way, we can monitor their overall dental health from the very beginning. For more information on children’s teeth, please read this article.

How many teeth to sharks have?


When we see younger patients at the practice, we love to give them some fun facts to go home with. A popular question we hear often is ‘How many teeth does a shark have?’. Sharks have THOUSANDS of teeth. Did you know that they can lose up to 100 teeth per day? The Great White Shark has around 3,000 teeth at a time, in multiple rows on their jaw. They are always growing teeth and will have approximately 30,000 teeth in their lifetime!

How many teeth to dinosaurs have?


We have been fascinated by dinosaur teeth for centuries. The truth is, different dinosaurs had different sets of teeth. There were so many different species.

The most talked about dinosaur, the T-Rex have around 60 teeth. The largest ever T-Rex tooth was found to have been 12 inches long. To fit all 60 teeth, the T-Rex jaw was said to have been around 4 feet long. The T-Rex had the most powerful bite force, and some teeth were as big as bananas.

On the other end of the spectrum, dinosaurs such as the Ornothomimus and Gallimumus did not have any teeth at all!

How many teeth to dogs have?
