The first teeth in babies normally erupt at the age of 4-7 months. But all babies are individual. If at 9 months the child has no teeth, then it is not always worth sounding the alarm. It can be a sign of a rare disease - anodontia, but not always.

Why does a child have no teeth at 9 months, and how many should there be?

Causes of missing teeth

The timing of the appearance of the first tooth is difficult to predict. For each baby, this process is individual, and in boys it erupts later than in girls.

The following factors influence the appearance of teeth:

  • Heredity. You should not wait for the first tooth until 9 months if it appeared in both parents after 1 year.
  • Infectious diseases of the mother during pregnancy. If a woman was sick in the period from 6 to 14 weeks, then this will negatively affect the condition of the baby's teeth.
  • Unhealthy lifestyle of mother during pregnancy.
  • Severe illnesses of the crumbs in the first months of life, for example, rubella, syphilis, gastrointestinal disorders. During this period, enamel and dentin are formed.
  • Rickets, deficiency of vitamin A, B, D, E, as well as lack of calcium and fluorine.
  • Sealing of baby's gums.
  • Individual features of the development of crumbs.

A rare but possible cause of missing teeth at 9 months can be anodontia. This is a genetic disease in which the teeth are absent.

What to do if at 9 months there is not a single tooth

It is worth waiting until the child is 1 year old. Often the first tooth can be found right after the birthday celebration. The symptoms of eruption are:

  • the baby is capricious and whiny, does not sleep well at night;
  • constantly puts hands in mouth, bites everything;
  • saliva flows profusely from the mouth of the crumbs;
  • the child has swollen and red gums;
  • body temperature may rise, diarrhea or vomiting may occur.

If after 1 year there are no teeth, and there are no symptoms of their appearance, then show the child to the doctor. You can check the presence of teeth with the help of x-rays.

How many teeth should a nine month old baby have?

On average, at this age there are 5 of them. Upper and lower front incisors appear, as well as one side. But this is a norm that not all children correspond to, and you should not worry about it.

To speed up teething, let the baby gnaw crackers or carrots.

Solid food rubs the gums and stimulates the growth of teeth. If you are afraid that the baby can bite off the cracker and choke, then buy special rubber rings - teethers, which are sold in pharmacies and children's stores.

Not a single child was left without teeth, so parents should be patient and wait. To speed up the teething process, you need to supplement the diet with calcium-containing foods.
