Do kids need a mouthwash too?

Prevention of dental caries is the main focus of a child’s oral health. Dental health forms an integral part of general health in a growing kid. But, in developing countries like India, owing to improper oral hygiene practices, overconsumption of sugars, and an unhealthy diet, dental caries continue to be the most common dental problem in kids. Ironically, studies report that children with poor oral health are 3 times more likely to remain absent from school because of toothache. 

Dental problems in growing children affect their overall quality of life due to recurrent infections, toothache, poor nutrition, sleeping troubles, emergency visits to dentists, inability to concentrate and improper growth and development. Thus, these facts highlight the significance of a good oral hygiene in kids. Brushing twice a day is the most basic and fundamental method to keep the mouth clean. In addition, use of a proper mouthwash under Dentist’s recommendation helps to give an extra boost to the oral health in children.

The need for a mouthwash in kids

Plaque and tar tar deposition on tooth surface is the initiating factor for tooth cavities and hence plaque reduction should be the hallmark of preventive dental care.

Even though these mechanical methods are extremely useful, population-based surveys conducted in India report that these methods are not employed properly and effectively.

Another study reported that, the use of fluoridated mouthwash along with toothbrushing significantly decreased the incidence of dental caries. A pilot study conducted on the urban school children reported that use of fluoridated mouthwash can strengthen the teeth up to 99%.

 The fluoride from the mouthwash bonds to the calcium and phosphorous from tooth structure to form fluorapatite which is more resistant to dental caries. Fluoride also helps in mineralization of tooth ie strengthening of the tooth and repair of the damaged tooth structure. Fluoridated mouthwash also interferes with the formation of plaque deposits and reduces the harmful effects of bacteria on the tooth surface. Thus, fluoridated mouthwashes have an excellent anti-cariogenic property and are most recommended by the Dentists as the best mouthwash for kids.
