Why animals' teeth are usually better than human beings' teeth?

It is not fair. As we use tooth brush, toothpaste, gloss, brushing liquid etc. However, our teeth are still not as durable as animals' teeth. Can anybody tell me why?

I have an idea and I am not sure if it is true or not. I have never really thought about it before... I think that first of all humans eat way too much sugar and chemicals and crap (not literally, of course... I hope) so it wears our teeth down more than it should. We are always brushing and flossing and all that other stuff. Maybe we just do TOO MUCH? I don't know.. sounds crazy, but I've heard stranger things! Also, animals do not care about having yellow teeth like we do... I think just in terms of evolution that perhaps our teeth have become much weaker than they used to be. Maybe humans used to have huge strong teeth.. haha I don't know!

That's sad that our teeth don't have the evolution as well as our mind and body.

Hello youless!:-) I don't think they have 'better' teeth than humans. I think every specie has teeth according to the requirement, most noticeably of their food choices as the basic function of teeth is to chew the food that is important for living and survival. I do think, however, that many animals have much stronger teeth than humans, but again, it's required for them to eat what they eat. They can not take care of their teeth for themselves, so they are already strong enough to fulfill their requirements. Having said that, I would agree with first responder that humans themselves make their teeth weaker by bad choices they make and sometimes by even taking too much care of their teeth i.e. going out of the way, using chemicals and such which may have side effects. At the end, I'll reiterate that every specie has what they need.

But obviously that dogs' teeth are better than human beings a lot. Sometimes I found the pets eat like human beings, but their teeth don't seem to have a problem and that's a myth. If we can find out why, perhaps it will be helpful for our teeth

It's always good to understand strengths of other creatures and exploit it for overall betterment!:-)

I guess it is because animals don't eat a lot of candies or sweets unlike us humans... even if we brush out teeth as often as we can... if we have the habit of eating a lot of sweets... then out teeth will decay eventually... aside for that... it has somethng to do with the saliva of the aminals...

The reason for animals having stronger teeth could probably be because of the type of food that they are eating. We, human beings only eat meat and vegetables unlike carnivores who eat also bones. This fact tells us that animals, particularly the carnivores has to have stronger teeth for adaptation.

If I start to eat bones, will my teeth become stronger?

Well, first of all what animals are you talking about? Herbivorous animals typically have teeth that continue to grow throughout their life or are replaced several times. Many animals have comparatively short life-spans, thus their teeth do not have time to rot. Finally, animals unlike humans have not removed themselves from evolutionary selection. An animal with poor teeth would die quickly, thus eliminating its genes from the gene pool. A human with poor teeth can survive to have many children with poor teeth! all the best urban

For example, dogs' teeth are very strong.

dogs live 15-20 years or there abouts, 29 is the oldest living dog I believe. Most peoples teeth are good and strong for 15 years or so. all the best urban

Hi youless! I really don't know why but probably because we love to eat sweets and candies. haha.. Seriously my dear friend, I have done a little research about this because I got curious but I haven't came across of any explanation why their teeth appears to be more durable than ours. Take Care and Happy Mylotting!

Hard to believe that scientists don't find out this reason yet. I think it'll be helpful for our teeth once they find out the secret. We invent many things according to animals, such as the radar.

Hi youless! I do hope so. Just like you, I have done everything my dentist tells me to do so to have stronger teeth and I do take calcium to have stronger bones and teeth. But I still have those weakening teeth and gums. I hope before I lose all of mine, they will discover something to prevent such thing in happening. haha..I hate to lose my two front teeth! Take Care and God Bless! Happy Mylotting!

Simple. They need their teeth to cut through fur and tough skin. We use knives and forks and some of us don't even eat meat.So we don't need our teeth to be as sharp.

That's a good reason. If we don't have tools to eat, perhaps our teeth will become stronger?

Eating well and having a lot of calcium should help to make your teeth stronger.

I think our teeth start off fine, it's just our diets tend to be very destructive. For example, I've had two small bottles of Dr. Pepper in the past 12 hours, I think that's a tad excessive.

I'd say its because we dont feed our pets candy and sugar. We go oh thats not good for them and eat it ourselves anyways.

Animals usually eat natural diets and do not have refined sugars and preservatives in their food. One dental study in particular found that people who took better care of their teeth by brushing and flossing and ate diets with refined sugars and packaged foods with preservatives had cleaner teeth, but had a lot of cavities. The other group of people from the same study were people who lived mainly on farms and in rural communities. Those people tended to eat a lot of fresh milk, vegetables, and meats. This second group had dirtier teeth, but when their teeth were fully cleaned, they were found to have far fewer cavities (or none at all) compared with the first group. Many animals will naturally eat things that help their teeth to be clean. This is probably one reason that dogs and cats like to chew on bones. The sharp bones can serve as an abrasive to somewhat clean the teeth. Cats and dogs that eat hard cat food that you buy in the store don't really need their teeth cleaned too much because the cat food somewhat helps to keep their teeth clean.

I would imagine they were designed that way so they can eat raw meat from other animals. Probably eating and chewing bones help to strengthen them too.

You are right. But when we were young we didn't know how to protect our teeth well. Until we grow up and we feel sorry about it.

i think it is because.. the animals do not eat as much 'junk-food' as we do.. we eat sugary, sweet things.. with all kinds chemicals, preservatives and what-nots.. i think people who lived before us had much better and stronger teeth also.. so.. it has to be because of the current environment that we live in..

It has to do with how animals evolved with their food. For most animals, they depend on their teeth to eat the raw, tough food that they need to survive. Human beings, for many thousands of years, has cooked their food and it became less necessary for humans to have large, thick enameled teeth like our ancestors once had. Also, the calcium and bone from those teeth could be used to further enlarge the brain case, for the brain has become the most important tool in our survival rather than our teeth like in animals.

That's reasonable.
