Here's a link indicating there could be an association between asthma inhaler use and tooth decay; washing out the mouth after inhaling is always a good thing to do.

Is asthma inhaler causing tooth decay?
Excerpt:
"I have done some research in order to determine if the medications are the cause of your son's cavities. The exact effects of both Beclovent and Albuterol on the teeth are
unknown at this time. About one percent of patients who use Albuterol for a long period of time experience tooth
discoloration. Patients who receive prolonged treatment with Beclovent may also show positive cultures for Candida
albicans, the organism responsible for yeast infections. In fact, up to 75 percent of patients treated with Beclovent may test positive for C. albicans. Yeast infections caused by C.
albicans occur more frequently in the mouth but may also occur in the throat region. Treatment for this infection may include antifungal therapy and/or discontinuance of Beclovent.
In addition, these medications may result in dry mouth, which can leave the teeth more susceptible to decay. It is highly
recommended to rinse the mouth after use of these inhalers as it may help mitigate adverse effects on the teeth and oral cavity. It is also very important that your son practice good oral
hygiene, which includes thorough brushing and flossing every day.

Hopefully, it will be possible to decrease the dosage of the asthma medications over time as this will also reduce any
side effects.

Thanks for your quick response. I recently saw an excellent Prosthodontist, who, in fact, suggested my soft tooth enamel & discolouration was caused by medication (but not tetracycline), genetics or diet. I will ask him about steroid injections when I see him next.
I do not know of any association between immunotherapy for allergic problems and teeth issues. If you received a series of steroid injections, this could possibly affect calcium absorption at a critical development period.
I am also not aware of a higher incidence of bruxism and asthma.
The expert to respond to these questions would be your dentist.
