My 2 year old has JUST started to have smelly breath????

[jkb]

Hello

My 2 & a half year old never had any smell atal from his mouth.. but for about 5 days now his breath really smells... like proper bad breath.. it lasts most of the day.. he hasent had any illness for weeks so its not related to a cold or anything.. The only thing I can think of is he only has 2 final teeth to get (the top back 2)..could the breath maybe be a sign they are on the way?? Has anyone else experienced a sudden change in breath in their child???should i take him to Gp?
any advice would be greatly appreciated.
(p.s.. i have looked up his nose & it seems clear & he is happily breathing through his nose.. so cannot see he has any object stuck up there or anything?)

Yes and it usually down to a sore throat.

How is he with toothbrushing?

My sister's 10 month old had this last week - was a throat infection.

he lets me brush his teeth really well...
wouldnt he be off his feed or ill if it were an infection?

Dd had really bad breath at this age - turned out where a tooth was breaking through the gum had become infected - the smell was the infection. Quick course of antibiotics sorted it out. Get to your gp!
