The age at which teeth erupt varies among individuals, generally within the normal physiological range of about a year. A normal child will erupt around 6 months after birth with a primary incisor, followed by a sequence of primary incisors, primary molars, primary canines, and secondary molars. At the age of 2 and a half, all baby teeth erupt, and there should be 20 baby teeth in the mouth at this time. The lower jaw teeth erupt earlier than the upper jaw teeth with the same name. When the head of the household discovers any abnormal situation, they should seek medical attention in a timely manner.
What to do if a newborn has teeth?
Generally, infants do not begin to have teeth until around 6 months old, but some infants have baby teeth growing in their oral cavity at birth, known as “birth teeth”. Some also have baby teeth growing in their newborn period, known as “new teeth”. Medically known as “congenital gingival deciduous teeth”. Refers to the teeth that sprout from birth to 30 days after birth. Generally, there may be one case among 2000 infants, with an incidence rate of approximately 0.05%. Parents should not panic. The reason is that the deciduous tooth germ is too close to the surface of the alveolar bone and the gum mucosa. This phenomenon is like scattering seeds on the surface of the soil, and the principle of breaking through the soil as soon as they sprout is the same. Birth teeth do not need to be treated as long as they do not cause difficulty in breastfeeding or become loose. If loose, you should go to the hospital for diagnosis and treatment, and remove the loose deciduous teeth as soon as possible to avoid aspiration into the trachea and suffocation after detachment.
Late eruption of deciduous teeth
If a child is over 1 year old or does not have their first deciduous tooth for a long time, the impact of systemic diseases should be considered. Such as rickets, minor illnesses, extreme nutritional deficiencies, etc. Some children suffer from congenital edentulous deformities, so they should go to the hospital for X-ray films to identify the cause of delayed tooth eruption
Increased drooling
Saliva, also known as saliva in medicine, is the secretion of salivary glands around the oral cavity. During the neonatal period, the salivary glands are underdeveloped and the amount of saliva is low. At the age of 6-7 months, teething begins. Due to the eruption of teeth, the gums become itchy and saliva secretion significantly increases, resulting in a high amount of mouth water during teething. Due to insufficient depth of the baby’s oral cavity, poor development of the nervous system and swallowing reflex, as well as poor control of saliva flow in the oral cavity, saliva often dribbles. This situation should be promptly wiped dry to keep the lower lip skin dry and clean. As age increases and teeth erupt, drooling will gradually disappear
Finger sucking and nipple biting
During teething, children love to bite their mother’s nipples, pacifiers, and their own fingers. This is due to the stimulation of gingival congestion and edema when teeth erupt, and children often experience discomfort such as itchy gums. Relieve itching discomfort by biting the nipples and sucking on the fingers. At this point, clean the baby with gauze, rubber wands, toys, or harder foods and have them bite to relieve the discomfort of itching on the gums
Emergent tooth hematoma
During the period of tooth eruption, some children may experience swelling of varying sizes on the gums near the eruption of their teeth, with a bluish purple surface and varying sizes of swelling, but it is limited to the cutting edge or surface of the tooth that is about to erupt. Swelling is caused by the process of tooth eruption, where the teeth penetrate the dental sac and accumulate blood under the gums. It appears as a small hematoma and is called an eruption tooth hematoma. Generally asymptomatic and does not require special treatment, it can be absorbed on its own.
