Yellow tooth?

Their teeth should be brushed twice a day with the correct concentration of fluoride in the toothpaste (one aimed at babies).

Formula actually does contain a fair amount of sugar (one study found more sugar in formula than fanta) and acid is almost as dangerous to teeth as sugar if not more so. Acid is found in most fruits etc and babies eat a fair amount of fruits I assume your baby has fruit puree?

Never brush teeth 30 mins after eating as you’ll just rub the sugar/ acid into the teeth and cause more of an issue.

I’d also say take baby to a dentist as even with these things a few months seems extreme to get a yellow spot.

Hope this helps x

There are sugars pretty much in anything, brushing twice a day for your baby once their first tooth comes through is necessary. As above I would get a dentist appointment to make sure everything is okay x

I believe Fluoride toothpaste should not be routinely used for children under 2 years old because they tend to swallow it, which could lead to dental fluorosis. It's recommended to use only a tiny amount, about the size of a grain of rice, if a child is at high risk for tooth decay and this is advised by a dentist. This is according to the CDC, WHO and ADA

the NHS suggests otherwise. To each their own though x
