Hello and welcome.
Thanks for sharing your concern.
I would like to suggest you to see your dentist
soon.An x ray
is required to see the extent of damage caused.
Please mention your age.?so that better diagnosis can be made in terms of eruption of teeth.
secondly please do not correlate other illness like nausea
and diarrhoeas with broken teeth.your physician can help you in this.
Please see your dentist soon so that clinical evaluation can be done and then if required a root canal treatment
Hope it helps.
