Sequence of how baby teeth come out

Now that our little champ has pushed out his first two teeth and we are (anxiously) awaiting the next ones to emerge I was wondering what the usual sequence for teething is anyway. Well - as it turns out the good people of the "Journal of American Dental Association" already did some research back in 1974 to answer exactly that question.

Eruption Sequence of baby teeth (also called "Deciduous Teeth" or "Primary Teeth") in months after birth:

TeethAverage "eruption" time (in months after birth)
1) Lower central incisor8 months
2) Upper central incisor10 months
3) Upper lateral incisor11 months
4) Lower lateral incisor13 months
5) Lower first molar16 months
6) Upper first molar16 months
7) Upper canine19 months
8) Lower canine20 months
9) Lower second molar27 months
10) Upper second molar29 months

Eruption time averages have been calculated among the general population (US). They are average values, so the variation can range ±6 months.

Interesting isn't it?

Hi Gorge - your dentist

Hi Gorge - your dentist should be able to confirm with an XRay.

Not that I'm competent to

Not that I'm competent to answer this question but I think the number of incisors actually varies between 4 and 2. Surprised to hear that your dentist wouldn't have a view on that?!?

Hi! My son is 9 years old and

Hi! My son is 9 years old and one of his upper front teeth(central incisor) is about to fall. Will a new teeth still grow to replace the old one??

Erm this is an interesting

Erm this is an interesting fact about me and my sister.We both only have 3 insicors in the lower teeth. We both are grown-ups. We are not twins but my mum is one. We have been to the x-ray and dont seen to have another tooth underneath . Is that normal? A dentist told my sis that it is pretty rare.

Hey Teknoliz - you need to go

Hey Teknoliz - you need to go and see a dentist I think ...

Hey I'm 12 and my second

Hey I'm 12 and my second upper molar has not come out yet . Why is that ? It hurts like crazy !

Very useful information

you are doing a good job

Hey - we're really not

Hey - we're really not qualified to give an opinion here ... especially since you've already asked your dentist. I'd suggest you get a 2nd opinion from another dentist (or a few other dentists) to see what can be done. Surely they would have done an X-Ray now to see whether the teeth are still in the jaw and are likely to come out when she loses her baby teeth?

Anyway - good luck and good health!

hi my daughter is 8 years old

hi my daughter is 8 years old in january, she doesnt seem to have developed her upper lateral incisors 2 im concerned coz my dentist says she should have them or they should of started to come through by now could you please tell me why or how this happens

Hi Zhaun - thanks for your

Hi Zhaun - thanks for your comment. We're no dentists of course so we can't really answer your question comprehensively. Children usually loose their 1st set of teeth some time between the age of 5 and 9, but again this age range can vary significantly from one child to the next. I have also heard of adults still having their 1st set of teeth. Perhaps it just means you've got really good dental hygiene.

Best wishes,

Stef

Based on that chart, if I

Based on that chart, if I understand correctly, the lower central incisors come through at 8 months old. I am 29 years old and still have my lower central incisors(baby teeth). The last time I had my teeth checked which was 2 years ago I didn't have any cavities on any of my teeth. My question then is at which age should the lower central incisor baby teeth have been replaced by adult teeth?

Hi Aili - I'd highly

Hi Aili - I'd highly recommend checking with a specialist before you opt for any drastic procedures like cutting the gum. As mentioned we are aware of several parents whose babies have not shown any signs of teeth until they were 12 months or more.

Hi there, i am a mama from

Hi there,

i am a mama from China.My mixed daughter almost 1 year now, has no single tooth.Shall we go to doctor and cut the gum? anybody has some idea
thank you sooooo much for some tips

Hi I Renick - based on the

Hi I Renick - based on the stories we have heard from other parents I don't think there is any cause for concern. It happens quite frequently that teeth don't come out in sequence (which is what happened with our little boy as well - see www.diyfather.com/content/Baby-teeth-eruption-out-of-sequence). The word we got from dentists is that they generally don't check children's teeth until they are 2 or 3 years old (depending on where you live). The central incisors of your grand daughter will probably come out in a few weeks anyway. As always, if you are worried about something just check with a health care professional - even if it's just to put your own mind at ease.

Best wishes

My granddaughter is 7 months

My granddaughter is 7 months old and got her first two lower cental incisors at 3 mos. Now we see that her upper lateral incisor has emerged before her upper central have come in...is there cause for concern?

Thanks Momz - good to know

Thanks Momz - good to know that they always come out sooner or later. In most stats I've seen it says that all 20 teeth should be there by the time they are 3.

My son started getting teeth

My son started getting teeth at 5mths. He's now 27 months and has 20 teeth :) And I have to say it has not been bad at all, I was dreading teething for him, but not so much of a cry or fever, there was just a lot of drool, lol

Hey tooth worrier - I'm with

Hey tooth worrier - I'm with you 100% ... Noah has just had all 4 molars (first molars) in ONE GO! The drooling, the nappy rash, the pain ... the stains. Ah well - we got through it and now he's the happy owner of 4 molars which come in really handy for chewing.

All the best!

-Stef

I am glad you decided to

I am glad you decided to post the research. I was freaking out when I just noticed my 10-1/2 month old was getting his 1st molars on the top. His teeth have a bit of a gap in the top and all I was thinking was the k9s were coming in way in the back. It also nice to now know why he has been fussy... never expected the molars to already come in! :) thanks again!

Again, seeing your baby's

Again, seeing your baby's first set of teeth is PRICELESS. It'll be nice if you can somehow capture a photograph of your baby's teeth. That will be a nice thing to show him when he grows up. Enjoy, Stef!

Every parent would really

Every parent would really find it interesting to know and to take a look at how their babies' teeth are growing. I know that they all look forward to the first tooth, then the second tooth until their babies have more 5 teeth!
