I enjoy red wine and tea but it’s made my teeth not as white as they used to be. I don’t like white strips because they irritate my gums. Whitening toothpaste doesn’t really impress me. Don’t want to spend a lot at the dentist for a bleach job. And my brother said the bleaching he got from his dentist did little for his teeth and he asked for a refund. Has anyone tried something they’re really impressed with? Thanks.
