1) Powder which is spread on dentures (false teeth) and placed in the mouth where it then mixes with the saliva to form a paste may not be used on Shabbos, according to many Poskim, as doing so is a prohibition of Lisha. (See Shmiras Shabbos K'Hilchaso Perek 14:35)
Some Poskim are lenient and do not consider this a transgression of Lisha. (See Shu"t Shevet Haleivi Vol. 4 Siman 32)
Other Poskim rule that although forming this "glue" isn't a transgression of Lisha, it is still prohibited due to the Melacha of Boneh.
For Halacha L'Ma'aseh, of course, a Rav must be consulted.
2) It is permitted to chew gum on Shabbos, as even though the gum and the saliva mix to form a thick mass, this is considered Derech Achilah, the normal way of eating and thus not subject to Lisha. (See Shulchan Aruch Siman 328:36)
Halachos for Shabbos Kodesh
1) One who transgressed the Melacha of Lisha on Shabbos is subject to the same guidelines as one who cooked on Shabbos, as follows:
If it was done intentionally (B'Meizid) the person who did it may not have any benefit from it ever, while other people may derive benefit from it immediately after this Shabbos. (Shulchan Aruch Siman 318:1)
If it was done inadvertently (B'Shogeg) he too may derive benefit from it once this Shabbos is over. (ibid.)
The Gaon of Vilna rules that when done inadvertently, the one who did it as well as anyone else may derive benefit from it even on this Shabbos. (See Mishna Berura Siman 318:7)
In cases of necessity we may rely on the Gaon's ruling (ibid.)
2) In situations where M'Ikar Hadin there is no concern of Lisha, and we are only stringent due to a Chumrah, a stringency, if it was done on Shabbos the item may be used. (See Biur Halacha Siman 321:16 Dibur Hamaschil Aval)

This brings us to the end of our journey into the Halachos of the Melacha of Lisha. I thank Hashem for giving us the opportunity to complete these Halachos and pray for Siyata D'shamya to begin and complete many other areas of Halacha together with you, my dear readers.
We will now take a small break from Hilchos Shabbos and start next week, B'Ezras Hashem, a new area of Halacha.
We shall, with Hashem's help, return to Hilchos Shabbos and the remainder of the 39 Melachos in the future.

Reader's Question:
What is the reason that a Kalah (Bride) and both mothers circle the Choson (Groom) seven times under the Chupah? Also, what is the source for this custom?
Answer:
There are many reasons cited for this custom.
One reason cited is that the seven circlings correspond to the 7 times it says "Kol" in the chapter of Mizmor L'Dovid Havu Lashem Bnei Ailim...(Tehilim 29) (Based on Tikunei Zohar Tikun 6).
Another reason cited is that the 7 circlings show that the marriage is being done in honor of Hashem who reigns in all 7 skies. (Sefer Sh'Eiris Yaakov Siman 18)
There are many other kabalistic reasons as well for this age-old minhag.
After originally posting this answer, 2 readers emailed me with the following additional reasons:
1) "I once learned that the kallah encircling the chosson 7 times is parallel to the 7 times that bnei yisrael encircled yericho- showing that the kallah is creating a spiritual choma/wall around her husband"
2) "Perhaps another reason for the 7 times (i think i saw this somewhere) is that there are 7 names for the yetzer hara and the new kalla is destroying him by having her new husband only focus on her so he won't come to sin with others."
