One year old baby has white spots on teeth

Some parents will accidentally find white spots on their baby's teeth, but many parents do not pay attention to it because the baby does not show other symptoms. If this continues, the condition will only become more serious, and may even directly affect the growth and development of their baby and cause some problems inside the teeth. In this case, you should take your baby for an oral examination in time to diagnose the cause of the disease as soon as possible.

Causes

Enamel demineralization is prone to occur during or after fixed orthodontic treatment. Enamel demineralization is the initial manifestation of caries. Early enamel demineralization is mainly the dissolution of the enamel prism interstitium and the loss of enamel surface mineralization, which is easily remineralized.

However, enamel demineralization always occurs during fixed orthodontic treatment, which may be caused by the following reasons:

1. The rough surface caused by acid etching of tooth enamel before bracket bonding and the surrounding area of ​​the bracket are prone to plaque accumulation;

2. The addition of archwires and other orthodontic accessories also hinders the cleaning of teeth. Many patients find it difficult to brush their teeth thoroughly with fixed braces in place, as plaque tends to collect around the brackets.

3. Studies have found that the number of mutans Streptococcus and Lactobacillus in the plaque around orthodontic brackets and rings and in saliva has increased, and their presence increases the risk of demineralization.

4. At the same time, the metabolism of supragingival plaque in orthodontic patients has also changed. The pH value of these plaques has decreased significantly, the carbohydrate content in the plaques has increased significantly, and the calcium and phosphorus contents have decreased, leading to an increase in cariogenicity.

5. In addition, orthodontic fixed appliances hinder the tongue's ability to move food particles, thereby stimulating the proliferation of acid-resistant bacteria, such as Streptococcus mutans; they also reduce the self-cleaning effect of food and muscle movement, reduce the contact between the tooth surface and saliva, accelerate plaque accumulation and pH drop. Plaque is not only a carrier of acid-producing substrates, but also delays the flow of acidic substances from the tooth surface, thereby hindering the remineralization of enamel by calcium and phosphorus ions in saliva.

Many patients who receive orthodontic fixed treatment will have chalky spots or plaques on their tooth surfaces, which clinically manifest as white spot lesions (WSL), i.e. enamel demineralization. If the lesions progress further, they may even form cavities. This phenomenon in patients receiving orthodontic fixed treatment has attracted more and more attention from dentists. A survey shows that the incidence of enamel demineralization after fixed orthodontic appliance treatment is 50% to 80%.
