Two Apagard tubes are printed "stain-care type". Before choosing between them, it helps to know which kind of stain a toothpaste can reach at all.
Surface stains only. Dentists sort discoloration into 2 kinds, extrinsic and intrinsic, and a toothpaste works on the surface, where extrinsic stains sit.
Tooth discolorations are typically classified as extrinsic, intrinsic, or a combination of both types.
Extrinsic stains commonly result from an accumulation of colored compounds on enamel.
Whitening treatments can be effective on both extrinsic and intrinsic staining.
Sangi makes two tubes for this. They share a type and differ in flavor and in the habit their cards name.
Neither card promises a shade or a deadline. The wording stays with stains and a fresher look.
Stain-care type
"A great option for coffee and wine enthusiasts seeking a fresher-looking smile"
Sangi's line for Serena, from the product card shown with the tube
Stain-care type
"Special formula to also remove stains (tobacco etc.)"
Sangi's line for Smokin', from the product card pictured with the tube
Serena. Its card is written for coffee and wine drinkers, and a 105 g tube costs $22.99. Smokin' is the same type in mild mint, with tobacco named first.
The 2021 review in Materials describes one explanation for the brighter look reported with hydroxyapatite pastes. It also notes the gap in long-term evidence.
Treat it as an explanation under study, not as a result you are owed.
As HA is white, it will reflect more light resulting in an increase in brightness
Extrinsic stains commonly result from an accumulation of colored compounds on enamel.
A tooth that has darkened from within will not answer to any toothpaste. The American Dental Association's sorting of discoloration exists for that reason.
If one tooth is darker than its neighbors, or the color changed after an injury, see a dentist before buying anything.
They are the same type, so pick by flavor and habit. Smokin' is mild mint at $24.55, and Serena is floral mint at $22.99. Both are sold 1 tube at a time.
