How likely is toothache in a toddler?

[BroccoliSpears]

Dd is 21 months old.
A few times recently she's been eating something and has suddenly cried out and said that her back, right teeth are sore. Obviously pretty uncomfortable for her.

Am thinking I'll phone the dentist just in case, but wanted to ask for thoughts here too.

We look after her teeth, brushing twice a day (for honesty's sake, we sometimes forget the morning one, but always have a really good do at night time).

She does have occasional biscuits and juice, but not every day - her diet is pretty good really.

Am hoping it's a back molar coming through.

Any experience?

it could be a molar, but its v early

have you had a good look around in her mouth? it could be a piece of food that lodged in and is causing her gum to be inflamed (my dd had this - i found what looked like an ancient but v small piece of food and a very red gum)

she is probably teething. But unfortuately tooth decay is possible even at this young age, and even when they have good dental hygiene - some children simply have bad teeth even though you do eveything possible to look ater them.

Good idea to get a dentist is check her.

or it could be mouth ulcers? Hand foot and mouth can cause nasty mouth ulcers, but she'd probably have a temperature as well

I've managed to have a good look with a torch and a good feel of the gum tonight.

Hard to say.

The gum where the molar will be seems scratched. Very firm, but no actual lumpy bits of tooth to feel.

Teeth look fine.

Am wondering how much the dentist will be able to achieve. Does anyone have experience of taking a toddler to the dentist for anything more than a rudementary check up? My dentist is wonderful, and she's been to him before so I don't expect hysterics, but I wonder if he'll just look and say he can't really see anything either.

She is a bit dribbly and off-colour. Maybe it's teething.
