Dead on!
👍 There is a reason my most in office systems reccomend follow up home bleaching to achieve the best results. Think about it

Bleaching in a nutshell is a function of bleach strength and time applied. Balance those 2 with patient comfort, and you'll get the best results
FOR THAT SPECIFIC CASE
On a side note, I notice a majority of the time that my patients that ask me about bleaching are the ones whose teeth are already a light shade to begin with (Vita A-2 or lighter), and those are the ones where I really need to take the time and give them a REALISTIC expectation about what bleaching could do for them, since most of them tend to think that their teeth are "awfull", "gross", "disgusting" or a variable host of other self depricating adjectives!
🙄 Without taking a few minutes of time to explain to this population, you'll end up with a patient who in all likelyhood whitened a few shades to B-1 or lighter, but STILL thinks their teeth are one of those great adjectives! Suprisingly enough this population tends to be females between the age of their teens to 40's
🙄 The same demographic that makes up the largest consumers of dental cosmetic proceedures!
