The last time I posted on this subject, some of the replies were so vile I left Mumsnet for a year.
I can remember reading a newspaper interview a paediatric dental consultant gave ? about 5 years ago, within this she discussed extended night breast feeding on demand and the number of these children having to undergo GA dentals at her hospital ( I think it was in the Daily Mail -sorry). Anyway, the online newspaper comments were awful, far worse than on this thread.
Her interview definitely mirrored our departmental experiences. Controversial but I very much doubt many UK general practice dentists have seen or experienced anything like the scale of gross caries that most Hospital/ Specialist / Community Paediatric dentists deal with daily in UK children. It's really easy for those within the specialism to become immune, so I think it's important to post ( when I'm feeling brave) on this type of thread from a different viewpoint.
I note you mention that your daughter's Upper lateral incisors are affected most severely, the central incisors less so; bottle caries manifests this way but I have seen the exact same pattern in children who've been nightly on demand breast-fed, within our GA service.
As soon as your daughter becomes cooperative enough, fissure sealing deciduous teeth may be possible. Most 6 year olds can cooperate enough for their newly erupted 1st permanent molars to be fissure-sealed. In my experience, not many general practice dentists do this routinely, so remember to nag yours or ask for a dental therapist/ hygienist referral instead. 3 monthly duraphat applications are a must going forward, not usually used in the under 3s but a case can be made for this in individual high-risk toddlers. There are prescription only fluoride toothpastes and rinses, but your daughter is too young yet and also, the local levels of fluoride in your water supply need to be taken into account.
Safe snacks- carrot sticks, cucumber sticks , cheese, toast & butter, crackers & cheese, plain ready salted crisps ( most crisps contain sugar) and tap-water to drink.
All sugar containing food & drink should be consumed strictly at breakfast, lunch ,dinner. Teeth have enough time then to remineralise between the 3 meals, Stephan's curve shows how the oral pH changes after meals.
