Question: What is the ruling concerning the use of toothpaste, ear
drops, nose drops and eye drops while one is fasting? If the one who is
fasting detects the taste of these in his throat what should he do?
Answer: Cleaning the teeth with toothpaste does not break ones fast
even when using the Siwaak, though one must make sure not to let
anything get into his stomach, but if anything should happen to get into
the stomach unintentionally then this does not break the fast. Likewise
eye and ear drops do not break ones fast according to the most correct statement of the ‘Ulamaa.
If one detects the taste of the drops in his throat, the ruling is for one to
be cautious and mindful but it is not obligatory since these drops do not
access the stomach like food and drink do, as for nose drops then they
are not permissible to use since they can enter the stomach so due to
this the Prophet (may the peace & blessings of Allah be upon him) said:
"When you make Istinshaaq (to snort water into the nose while
making ablution) then snort the water excessively unless you are
fasting."
So the ruling applies to the one who does this based on the narration
and by what has been conveyed from its meaning, if one should detect its
taste in the throat and Allah is the Protector of Success.

And ash-Shaykh Muqbil bin Haadee al-Waadi’ee (rahimahullah) was
asked: What is the ruling concerning the following: Using Siwaak and
toothpaste?
Answer: As for using the Siwaak made of al-Araak then there is no harm
in it even if it is still green, but in regards to using toothpaste then we
advise that it not be utilized during Ramadhaan, we do not have evidence
that it breaks ones fast but it is incumbent that one prevents anything
from passing into his stomach, the Prophet (may the peace & blessings of Allah
be upon him) said:
"When you make Istinshaaq (to snort water into the nose while
making ablution) then snort the water excessively unless you are
fasting."
Because when one is fasting he should fear water getting through to his
stomach.
