Frequent between-meal snacks that are high in sugars and starches may be more harmful to teeth than eating such foods at meals and then brushing.
Is it true that frequent between-meal snacks that are high in sugars and starches may be more harmful to teeth than eating such foods at meals and then brushing?
Yes. Frequent between-meal snacking, particularly on items high in sugars and starches, is consistently linked to an increased risk and severity of dental caries compared to eating during structured meals.
Verdict: SUPPORTED · 3 sources for, 0 against · Last checked
Multiple studies indicate that the frequency and timing of between-meal snacks, especially those containing sugars and starches, play a major role in the development and severity of dental caries. No provided studies refute the claim that frequent snacking is harmful to dental health.
