Should you rinse your toothbrush with soap? Here’s what a dentist has to say

What happens if one washes their brush with soap?

“Firstly, there’s a risk of ingesting soap residues, which can cause gastrointestinal discomfort. Additionally, if the soap is not rinsed off thoroughly, it can leave an unpleasant taste on the toothbrush, impacting the overall brushing experience,” shared Reddy.

Moreover, soap residues left on the toothbrush may not effectively eliminate all bacteria, leading to concerns about compromised oral hygiene, he added.

How can you keep your brushes clean?

“To keep toothbrushes clean and minimise bacterial growth, the ADA recommends rinsing toothbrushes with water after each use and allowing them to air-dry upright in an open area,” said Dr. Reddy.

He advised against covering toothbrushes, as this creates a moist environment conducive to bacterial growth.

He emphasised the importance of regularly replacing toothbrushes every three to four months, or sooner, if the bristles become frayed, to maintain optimal oral hygiene.

For those seeking extra precautions, he suggested soaking toothbrushes in an antibacterial mouthwash or using a toothbrush sanitiser as viable alternatives.

He also mentioned a 2016 study conducted by Adil Basman et al., which suggests that submersion in 50 per cent white vinegar is an effective and cost-efficient method for disinfecting toothbrushes at home.
