Based on Ruby's feedback, the Whitening Gel Toothpaste with Fluoride by MOON Oral Care seems to be a promising option for those looking to enhance their teeth whitening routine. The toothpaste's pleasant taste and non-gritty texture make it a comfortable choice for daily use. While Ruby didn't mention any drawbacks, it's important to note that individual results may vary and it may take some time to see significant whitening effects.
