(CBS) It may not be smart to retain your wisdom teeth, new research indicates.

Wisdom teeth are the molars that are farthest back in your mouth, Dr. Nancy Rosen told The Early Show co-anchor Harry Smith. They come in between the ages of 17 and 25.

They're called "wisdom teeth" because people are said to get wiser during that time.

Smith asked Rosen, his personal dentist, why she hasn't suggested he have his wisdom teeth removed.

"Yours are fully erupted," she said, "meaning they are aligned, they are above the gum tissue, and they are clean as a whistle. So you can keep them."

But if they're not fully erupted, Rosen said, it can be a problem. "It can cause an opening around the tooth and bacteria can get around the tooth, cause swelling, infection, inflammation, and a lot of pain."

According to new research, Rosen says, if you can't keep wisdom teeth clean, "a lot of plaque is going to accumulate around them. This is going to cause infection, gum and bone disease, and this can increase the risk of premature birth or it can complicate other health problems, like heart problems or diabetes."

She advises asking your dentist whether you should have your wisdom teeth removed. "They just need to take an X-ray and evaluate the position and if there is any decay, or if you're able to keep them clean."
Removing them can be a pain. Literally.
"I'm not going to lie," Rosen said. "It is definitely a little uncomfortable. But I think if you need to have them taken out, the pros outweigh the cons."

God and the man
A man visits God and says "God, do you mind if I ask you a few questions?" God says "No, ask me anything at all." So the man says "God, you've been around for a very long time,
so, for you, how long is a thousand years?"God replies "For me, a thousand years is only five minutes." The man then says "That's interesting God. And, for you,
how much is a million dollars?" God replies "For me, a million dollars is only five cents."
The man says "Really? Well then God, could you lend me
five cents please?" God looks at the man, smiles, and says "Of course my son.
Just wait five minutes!"
Genie joke
A woman is walking along a beach when she finds an old oil lamp.
She picks it up and rubs it, and out comes a genie.The genie says to the woman, "Thank you for freeing me from the oil lamp.I will grant you three wishes, but whatever you wish for, your horrible ex-husband will get twice as much. What is your first wish?"The woman says, "I'd like a million dollars in my bank account, please!" The genie says, "You now have a million dollars in your bank account, and your ex-husband now has two million dollars. What is your second wish?" The woman says, "I've always wanted a nice car. I'd like a brand new Rolls-Royce, please!"
The genie says, "You now have a new Rolls-Royce in your garage
at home, and your ex-husband now has two new Rolls-Royces.
What is your third wish?"The woman thought for a while and then said, "I'd like you to remove one of my kidneys, please!"
What's 3 x 2? A little boy returned home from school and told his father that he
had failed the maths test. His father asked him, "Why did you fail?" The boy replied, "The teacher asked me 'How much is 3 x 2?' and I said
'3 x 2 is 6'." "Well, that's right" said his father. The little boy continued, "Then she asked me 'How much is 2 x 3?" "What the hell is the difference?" asked the father. The son replied, "That's exactly what I said to my teacher and that's
why I failed the maths test.
2 x 11 Why is two times ten the same as two times eleven? Because two times ten is twenty, and two times eleven is twenty, too!
