Vet says pet will get flouride poisoning

[drmalernee]

Client question e-mailed to me today

Hi,

In speaking to people here at work in reference to the teeth solution I picked up for XXXX yesterday, a couple have decided to check with their Vets to get the solution. One Vet told a woman that it's not a good idea to use that daily, as the animal could get flouride poisoning. Is this a trueism, or is the solution weak enough to not matter? Just curious.

answer

There are different types of fluoride used in dentistry. I Promote stannous not sodium fluoride because studies show it is safe (see first study below) and works better than other fluorides. (see study 1 below)

Fluoride tablets are being used as treatment for other non dental diseases (see study 2 below). The reason stannous fluoride is no longer used in most human tooth paste is because of accumulation of extrinsic tooth stain. (see study below) Crest toothpaste had stannous Fluoride in it when I used it as a child but the other types of fluoride leaves the teeth with less stain. (see study 1 below)
good luck,

The effects of a stabilized 0.454% stannous fluoride

After six months, the stabilized stannous fluoride dentifrice significantly reduced gingivitis and gingival bleeding by 20.5% and 33.4% compared to the sodium fluoride control group.

As expected, accumulation of extrinsic tooth stain was greater in the stabilized stannous fluoride group
snip
No unexpected nor clinically significant oral soft tissue health effects were associated with the use of the test dentifrices. The results from this clinical study demonstrate that over a six-month period, twice-daily use of a dentifrice containing 0.454% stabilized stannous fluoride significantly reduced gingivitis and gingival bleeding, relative to a 0.243% sodium fluoride control dentifrice.

Sodium fluoride: effectiveness of treatment for cochlear otosclerosis.

Forquer BD, Linthicum FH, Bennett C.

We examined the effectiveness of sodium fluoride in treatment of cochlear otospongiosis in ninety-four patients with cochlear otosclerosis and ninety-eight patients with stapedial otosclerosis and sensorineural hearing loss. The drug halted or slowed the progression of sensorineural hearing impairment in 63% of the patients with cochlear otosclerosis and 46% of the patients with stapedial otosclerosis. The single factor that best predicted which patients would respond most favorably to treatment was rate of progression before treatment. Sodium fluoride therapy was successful for 79% of the patients losing their hearing at a rate of 5 dB or more per year at one or more of the speech frequencies. The finding that patients with more rapid rates of progression responded most favorably to sodium fluoride therapy suggests that patients with the most active otospongiotic processes will be the most responsive to treatment.

Pigmented-anaerobic bacteria associated with canine periodontitis.

The etiology of human periodontal disease has been the focus of considerable research, yet relatively little is known about the causative agents of companion animal periodontitis. In humans, Porphyromonas gingivalis, a black-pigmented anaerobic bacteria (BPAB), has been implicated as the primary periopathogen. It has been demonstrated that BPAB are also found in companion animal periodontal pockets. While some animal BPAB have been individually identified, a study to identify the most frequently isolated subgingival BPAB has not been completed using genetic tools. The objective of this work was to identify the types and relative frequencies of pigmented anaerobic bacteria found in the periodontal pockets of dogs. Porphyromonas salivosa, Porphyromonas denticanis (a novel species) and Porphyromonas gulae were found to be the most frequently isolated BPAB associated with canine periodontitis.
